List of uniform honeycombs

Postby polychoronlover » Fri Jan 02, 2015 5:55 am

Hello everybody! Polychoronlover here. I joined back in 2012, but I never posted because then I kind of forgot about polytopes for a while. However, I recently made a list of all uniform tessellations of 3-dimensional space (honeycombs) that I know of, including non-convex ones. (Kind of like a 3D version of this list of uniform tilings http://en.wikipedia.org/wiki/Uniform_tiling#Expanded_lists_of_uniform_tilings) It was mostly inspired by Jonathan Bowers' work on uniform polychora, including the symbols I used. I attached my list here.

Hmmm,
as I get it, I'll have to add some further symmetry groups to my page on euclidean tesselations, at least those (any other ones as well?)
Code: Select all
(o(oo),o) = o3o3o3o3/2*a3*c
o'oo"o = o4o3o4/3o
o"oo"o = o4/3o3o4/3o
o8"o = o3o3o *b4/3o
o'(o'o"o) = o4o4o4/3o3*b
o'(o"o'o) = o4o4/3o4o3*b
o"(o"o'o) = o4/3o4/3o4o3*b
o(o"o~o') = o3o4/3oinfino4*b
o(o,o~o) = o3o3/2oinfino3*b
(oo'o"o) = o3o4o4/3o3*a
(("o~(o'o)~o")') = oinfino4/3oinfino4/3*a4*c *b4*d

(o"o~o') o~o = o4/3oinfino4*a oinfino
(o,o~o) o~o = o3/2oinfino3*a oinfino
o'o"o o~o = o4o4/3o oinfino
o"o"o o~o = o4/3o4/3o oinfino
oo^6/5o o~o = o3o6/5o oinfino
(o^6o^6o,) o~o = o6o6o3/2*a oinfino
(o~o^6/5o^6) o~o = oinfino6/5o6*a oinfino
(o^6o^6/5o) o~o = o6o6/5o3*a oinfino

(o"o~o') o = o4/3oinfino4*a o
(o,o~o) o = o3/2oinfino3*a o
o'o"o o = o4o4/3o o
o"o"o o = o4/3o4/3o o
oo^6/5o o = o3o6/5o o
(o^6o^6o,) o = o6o6o3/2*a o
(o"o~o') o = o4/3oinfino4*a o
(o~o^6/5o^6) o = oinfino6/5o6*a o
(o^6o^6/5o) o = o6o6/5o3*a o
o~o o o = oinfino o o
o~o o o~o = oinfino o oinfino


Also some of the therefrom derived honeycombs are already listed in that file of polychoronlover. I would like to know whether Jonathan Bowers already has elaborated all the according OBSAs (official Bowers style abbreviations, ;) ), or could else provide them?

From a private reply:
Hedrondude wrote:I call (x'x"x~) satsa.

I played with some of these before by sketching their verfs and getting regiment counts, although I have yet to list them in a spreadsheet.

Here are some good names to start with:

o'ox"x = quitch
o'xx"x = gaqrich
x'xx"x = gaquapech
x'ox"x = quiprich
x'xo"x = paqrich
o'(o'x"x) = gacoca - for great cubaticubatiapeiratic honeycomb
o'(x"x'o) = wavicoca
x'(o'x"x) = skivpacoca
o(x"x~o') = wavicac - sphenoverted cubitiapeiraticubatic honeycomb

I'll coin more soon.

Jonathan B.

Above missing long names thus most probably read:
Code: Select all
quitch     - quasitruncated cubic honeycomb
gaqrich    - great quasirhombated cubic honeycomb
gaquapech  - great quasiprismated cubic honeycomb
quiprich   - quasi prismatorhombated cubic honeycomb
paqrich    - prismatoquasirhombated cubic honeycomb
wavicoca   - sphenoverted cubaticubatiapeiratic honeycomb
skivpacoca - small skewverted prismatocubaticubatiapeiratic honeycomb


Btw. "satsa" is the abbreviation of: squariapeirotruncated squariapeirogonal tiling

Oh yeah, I should disclaim that some of the acronyms I listed, including the ones for nonconvex honeycombs, were made by me because I didn't know what the real acronyms were.

The convex uniform apeieotera are as follows.

1. Wythoffian.
2. Wythoff snub (1) s3s4o3o3o
3. Laminates LB3, LC3, LPA3, LPB3, LPC3, LC1A2, LC1B2, LC1C3.

Among the non-convex ones, one has the isomorphs in 4/3. the Wythoff altisnub s3s4/3o3o3o, and the laminaes LPx3, LCA1 and LCA3 have isomorphs.

Hehe Wendy, polychoronlover and I just were after the non-convex apeirochora, not the apeirotera ...
But good to know - even so your lamiate namings surely are hard to decode ...

I presume "lamiate" is a tiling that utilizes a mythological human/snake hybrid? :)

I make there to be ten starry apeirochora, that is, tilings in 3D, not counting the prismic groups.

.4.3.4. gives xxox xxxx xxoo xoxo xxxo all together 5
.4.3.A. gives xoxo and xxoo all thgether two
The laminates give LLPA2, LLPB2, LLPC3, all together three.

Ha,
Code: Select all
4. (o(oo),x) = o3o3o3x3/2*a3*c | Tetrahedral hemitriangular tiling honeycomb. Cells are tets and trats (triangular tilings). Verf is an oho. Symbol is (o(oo),x). This one has hemicubic honeycomb symmetry, but is only wythoffian if it has quarter cubic honeycomb symmetry, also known as cyclotetrahedral symmetry.
19. (o(xx),x) = x3o3x3x3/2*a3*c | Truncated tetrahedral hemitriangular-tiling honeycomb. Symbol is (o(xx),x). Cells are tuts, hexats (as truncated trats), and ohoes. Verf is a crossed quadrilateral pyramid. This has hemicubic honeycomb symmetry.

the first 2 of these 3 Dynkin symbols are wrong. Consider
Code: Select all
(B(CA),D) = A3B3C3D3/2*a3*c =
      _A_     
  _-3- | 3/2_ 
 B_    3    _D
   -3-_|_-3-   
       C       

They rather should be
  • (x(oo),o) = o3x3o3o3/2*a3*c with cells o3x3o3.3/2*a3*c = trat, o3x3.3o3/2*a3*c = tet, o3.3o3o3/2*a3*c = vertex (verf=oho), .3x3o3o3/2*a3*c = tet - thus indeed what no. 4 described (but not the there given symbol)
  • (x(xx),o) = x3x3x3o3/2*a3*c with cells x3x3x3.3/2*a3*c = hexat, x3x3.3o3/2*a3*c = tut, x3.3x3o3/2*a3*c = oho, .3x3x3o3/2*a3*c = tut - thus indeed what no. 19 described (but not the there given symbol)
  • (o(xx),o) = x3o3x3o3/2*a3*c with cells x3o3x3.3/2*a3*c = that, x3o3.3o3/2*a3*c = oct, x3.3x3o3/2*a3*c = oho, .3o3x3o3/2*a3*c = oct - thus indeed what no. 33 described
If I not misread or even overread something, so the further here possible case is missing:
  • (o(xo),x) = o3o3x3x3/2*a3*c with cells o3o3x3.3/2*a3*c = trat, o3o3.3x3/2*a3*c = tet, o3.3x3x3/2*a3*c = oho, .3o3x3x3/2*a3*c = tut
(All others of this specific symmetry (o(oo),o) would ask for some Grünbaumian cells like a double cover of tet, of oct, of tut, or of thah, if not even severals of these.)

Thanks for pointing out my errors! Were there any other errors, or known honeycombs that I missed?
Also, are Paqrich and Quiprich distinct? The only nonconvex prismatorhombate regiment I could find contained something I called the prismatoquasirhombated cubic honeycomb as the second member. But that was x"ox"x, not x"ox'x or x'ox"x.

EDIT: When I wrote x'ox"x as the symbol for the honeycomb in my document, I meant x"ox"x.

EDIT: When I wrote x'ox"x as the symbol for the honeycomb in my document, I meant x"ox"x.


Actually all of these are distinct: x'ox'x (convex), x'ox"x (starry with convex verf), x"ox'x (starry, crossed verf), x"ox"x (very starry, crossed verf) - we could call the last one quipqrich for quasiprismatoquasirhombated cubic honeycomb - its a bit more "quasier" :mrgreen: . We can also call x"xx"x - quequapech for quasiquasiprismated cubic honeycomb.

I noticed that number 25 and 28 were the same, one of them should have coes and thas in it. Number 26 should have octs, hohas, and ohoes. It also appears that the rich regiment has 45 members, this is due to the alternate symbol (oxox) where the two squares in the verf can now be considered as two different groups of octs in the honeycomb, making the rich regiment behave similar to the afdec regiment. Unlike the afdec regiment, the rich regiment has hemicells, therefore a different regiment count. The regiment with a square frustrum verf will also behave like afdec, I suspect it has 58 members due to the top and bottom square being different sizes.

Also the ionic ones in the octet regiment will crash :cry: , this is because it will cause the octahedra to have one square face active and all edges active, which will have a verf shaped like a percentage symbol % (bar for the square, two points for two edges) at four vertices, but would look like four points :: at two vertices - so the verfs of the octet members would need to have four of the six squares of co to look like % and two like :: in order to have any chance of working, instead of all of them like %.

Code: Select all
140. (("x~(o'x)~x")') = oinfinx4/3xinfinx4/3*a4*c *b4*d | Discubicuboctahedral alternate square disquare apeirogonal tiling honeycomb. Symbol is (("x~(o'x)~x")') Cells are soccoes, goccoes, shas, and disquas.

does not work either.

Sure, you well can consider the symmetry groups
Code: Select all
         o         where
        /|\       
       / P*\       P =  3,   4,   6
      /  |  \      P* = 3/2, 4/3, 6/5 (resp.)
     U  _o_  P     U = infin (always)
    / _P   U_ \   
   /_-       -_\   
  o------P*-----o 

provided one ringed node at any U-link at least. But this then becomes a degenerate group: none of the cells would be truely 3D, all being flat tilings only!

Btw. one likewise can consider the following groups generally:
Code: Select all
         o         where
         |         
         3         P =  3,   4,   6
         |         P* = 3/2, 4/3, 6/5 (resp.)
        _o_        U = infin (always)
      _P   P*     
    _-       -_   
  o------U------o 

again provided one ringed node at the U-link at least. This works well for P=3 and P=4, as then at least some true 3D polyhedra occur for cells. But the case P=6 similarily does produce only tilings for "cells". Therefore this latter case again is degenerate!

Btw., I did not say anything about the existance of an honeycomb with soccoes, goccoes, shas, and satsas (= disquas). I just refer to that provided symbol, which definitely does neither produce these cells, nor even will produce any non-degenerate honeycomb.

I am working on an updated list of uniform honeycombs now. It will probably be ready in a few days. Meanwhile, is there a reason the Wikipedia page "Uniform tiling" doesn't seem to list the rhombisnub uniform tilings on Klitzing's site?

Sadly there are 2 contracurrent streamings on Wikipedia:

- On the one hand it is open for anyone to add content, even new pages. At best when additionally be logged in, i.e. having an personal account, so that the changes can be tracked to a person instead of an IP-address only (which furthermore might change, depending on one's internet provider).
- On the other hand there have been lately lots of hardliner remakes, allowing only for assured content, i.e. only such which have any printed reference. Websites currently are accepted only in addition as a crossreference, but not as its sole reference.

To my personal knowledge e.g. Tom Ruen generally struggles with diligently adding lots of polytopal contents to wiki, whereas e.g. Guy Inchbald rather takes on the opposite position ...

Thus it is more a question of speed: contributing much more content as can be deleted again. And hoping on change of politics ...

I.e. feel free to provide content to Wikipedia whenever you feel like there is something missing! But likewise it might also occur that your contributions gets edited by others as well or even get deleted again ...

At least you should know that nothing on any website so ever is static. Content gets changed every now and then, URLs might no longer work, etc.



Wrt. capirsit = celliprismatorhombisnub icositetrachoral tetracomb = s3s3s4o3x the corresponding problem would be that my formal extension of snubbing devices, i.e. the alternated facetings (which since then allows for arbitrary mixtures of s, o, and x nodes in Dynkin symbol decorations) well were described in a printed reference (cf. "Snubs, Alternated Facetings, & Stott-Coxeter-Dynkin Diagrams", published at: "Symmetry: Culture and Science", vol. 21, no. 4, 329-344, (2010) - also available in electronic form here), but this very paper explicitely deals with its application onto the group o3o4o only (for obvious publishing reasons). So s3s3s4o3x therefore would not be captured thereby explicitely ...

Btw., you speak of "rhombisnub uniform tilings" (plural). Which else do you refer to?

Here are two images from the Wikipedia page "Uniform tiling". The nonconvex tilings they list, in order, seem to be:
    Ditatha, sha, tha, hoha, shothat, sraht, sossa, sost, gossa, shaha, ghaha, huht, ghothat, graht, qrothat, satsa, hatha, qrasquit, quitothit, thotithit, quitsquat, quothat, retrat, rasisquat
which skips rassersa, rarsisresa, rosassa, and rorisassa from bendwavy.org, as well as chatit, which I think is degenerate.
By the way, here is my list of antifrustumverts from the rich regiment, but I'm not sure that I got them all. I used Stella to step through facetings of the verf. Did I miss any?
Code: Select all
283. Octahemioctahedral tomoctahedral hemitrihexagonal tiling honeycomb. Cells are ohoes, toes, and thats.
284. Tomoctahedral intercepted disoctahedral cuboctahedral cubohemioctahedral hemitrihexagonal tiling honeycomb. Cells are octs (in two orientations), coes, choes, toes, and thats.
285. Tomoctahedral intercepted disoctahedral octahemioctahedral hemialternate hexagonal tiling hemialternate triangular tiling honeycomb. Cells are octs in two different orientations, ohoes, toes, hohas, and thas.

I know it's bumping an old thread, but I have a question related to this: Has anyone investigated the starry 4D honeycombs yet? There are some interesting regiments there that I'm somewhat curious how to count. For reference, I will post the convex 4D honeycombs and what I know of their regiments...

o'ooo'x = x'ooo'x - test. Verf is hex. Should act like the scad regiment with 11 main members, but also some prismatic and duoprismatic ones.

o'xoo'o - rittit. Verf is taller octahedral prism. Should act like the rat regiment, at least 44 members. However, there should also be a subsymmetry (o'oo9x, I think) whose verf is an oct podium, which probably adds more.

o'oxo'o - icot (birectified test). Verf is a tes, not sure how many here.

o'oox'x - tattit. Verf is oct pyramid. 2 members.

o'oxx'o - batitit. Verf is square disphenoid. 2 members.

o'oxo'x - srittit. Verf is a square prismatic wedge, acts like the sart regiment. 93 members.

o'xox'o - ricot (birhombated test). Verf is duowedge, but should have fore than sibrant, as not only does it have a half symmetry, but also quarter symmetry ($o$).

o'xoo'x - sidpitit. Verf is a trigonal antifastegium, due to half-symmetric representation it acts like spat. 85 members.

o'oxx'x - grittit. Verf is square scalene. 2 members.

o'xxx'o - ticot (great birhombated test). Verf is disphenoid pyramid. 1 member.

o'xxx'x - gippittit. Verf is line tettene. 1 member.

x'xxx'x - otatit. Verf is irregular pen. 1 member.

o'xox'x - potatit. Verf is wedge pyramid, but can be given half symmetry. 11 members.

o'xxo'x - prittit. Verf is trapezoidal disphenoid. 3 members.

x'xoo'x - capotat. Verf is trigonal antipodic pyramid. 7 members.

x'oxo'x - scartit (@hedrondude: I suggest changing this one to "cartit" to match with the polytera). Verf is antiduowedge. 18 members.

x'oxx'x - gicartit (@hedrondude: I suggest chaning it to cogratit to match with polytera). Verf is trapezoidal scalene. 3 members.

x'xox'x - captatit. Verf is trapezoidal scalene. 3 members.

Any information on missing ones? If I get feedback, I will analyze the rest of the convex ones.

I was looking into these a bit. One of the more interesting things I found was a family with diagram like so: o3o3o4o3o4/3 *a. It includes the lieutenant of the x3o3o4o3x regiment, as well as the head of its conjugate regiment, a "double-covered" version of a o3o3o4x3o, and even some afdec-like members with vertex figures of the form a b3o || c o3d. These regiments seem to even include afdec members as potential facets, and may have over 1000 members!

Also, I found a "novel" tetracomb (one that does not have anything with a linear diagram in its regiment), o4o3o4x4/3x3 *c. It is interesting because the vertex figure is an octahedral podium whose "crossed" faceted form creates the conjugate, while a similar spherical polyteron, o3o3o4x4/3x3 *c, has a tetrahedral podium as its verf, whose crossed form is an antipodium instead.

oNo3o4x4/3x3 *c is also the only member of the oNo3o4o4/3o3 *c family which is not "skewed", does not contain cotcoes, and does not share its regiment with a polytope of the form ...x3o4/3x. It's interesting how it's so different in each case.

One other interesting one should be x3o4o3x3o, which has a square antifastegium verf. I'm pretty sure this one has a conjugate, but not sure about the symbol.

Indeed, that's curious, but a similar thing happens in lower dimensions. Take o3o3x4/3x4*a, which has a triangle podium, its crossed faceting is a trigonal crossed antipodium. o4o3x4/3x4*a has a square podium verf, and its crossed version is a square crossed podium. (In spherical 4D there is a regiment with a pentagon podium verf, and one of that one's crossed members has a pentagonal crossed antipodium verf.)

Fun fact, the edges of o3x3o4o3x are a subset of the edges of x3o3o4o3x! This is similar to how the edges of o3x3o4x are a subset of those of x3o4o3x. Adding more edges increases the symmetry; however, when applied to tesselations in affine geometry, the symmetry can be "increased" or "decreased" just by zooming in or out. And that's what happens in the case of o3x3o4o3x and x3o3o4o3x -- they have the same symmetry, but when the edge lengths are the same, x3o3o4o3x is more densely packed with symmetrical modules. If we were to superimpose those tetracombs over each other, the size of x3o3o4o3x would have to increase for their symmetries to line up.

This is because the square antifastegium vertex figure of o3x3o4o3x is just the cube - octahedron antipodium vertex figure of x3o3o4o3x, minus two vertices.

The conjugate of o3x3o4o3x is o3x3o4/3o3x. The head of its regiment also has a square antifastegium vertex figure, and the symbol o3x3o4o3x4/3 *b.

Re: List of uniform honeycombs

Neat one. Wonder if there are any other relationships like that...

I think icot (tes verf) and hext (ico verf) may be related like that, since tes's edges are a subset of ico's. There are probably a few more like that.

I think I figured out what one of the afdec-types is. Its CD diagram is (I'm not sure of the linearization, so here's a rough idea):

Code: Select all
   o
   3
   o
3   4
x 4/3 x
4   3
   o


This thing has as facets rits, ricoes, gittiths, and afdecs. The verf is a q x3o || x q3o (the bases being rit and rico verfs, and connected by the gittith and afdec verfs).

One thing is, I'm fairly sure here that afdec acts like it has more members than it actually does. The two sets of 24 coes in the afdecs behave differently (one set connects to rits while the other connects to ricoes), and the goccoes are simila"r (one pair connects to gittiths, the other connects to more afdecs). This is why the "a" and "b" sets of goccoes (as listed on Hedrondude's afdec page) are different, so the afdecs here should act closer to affixthi and have 99 members.

BTW, I noticed after your latest revision of the list of honeycombs, you posted a list of new ones. Did you ever get around to adding those to your list of honeycombs? In particular I'm curious about the one with a trigonal cupola verf - does it act like the stut phiddix regiment of 4D?

Yes indeed, the hext regiment is home to a compound of (I think 4) icots! Its vertex figure is a gico, a compound of 3 tesseracts. Furthermore, there is a compound of tesseractic tetracombs (tests) in the icot regiment, two meeting at each vertex. They act like they have demitesseractic symmetry, though. There is also a compound of tests in the hext regiment, this time with full symmetry and meeting 3 to a vertex.

About the afdec-containing regiments, you're right about afdec acting like affixthi, because the contic symmetry doesn't show in this regiment. There should be 98 possible types of cells in the vertex figure that can appear in place of afdec's verf, and sometimes nothing will be there at all.

The vertex figure looks like nit's vertex figure, a tisdip, but with less symmetry. That means it will have more facetings, which leads to more regiment members. There should be one figure corresponding to each of the 24 nit regiment members with pentic symmetry and two corresponding to each of the 125 members with demipentic symmetry. So there are at least 274 tetracombs in this regiment, and probably a lot more.

I've given up on updating that list. It was becoming too complicated trying to fill the gaps in my numbering with newly discovered honeycombs, and then I discovered so many more that I was too lazy to add. Plus, I kept noticing errors that had crept into my original list. I'll make a new one eventually, though, with brand new numbering.

If you mean the triangular tiling antiprism, then no. This is because the edges in the verf that make up the lacing between the triangle and the hexagon don't correspond to a face with an even number of sides. Also, where the stut phiddix regiment has srids as possible cells, this figure has apeirogonal antiprisms (azip). Since azip does not have any other regiment members, this forces the honeycomb's regiment to be smaller. (For a 3-dimensional analogy, think of how the antiprisms and cantellates both have trapezoidal verfs, but only the cantellates have regiments.)

I'm pretty sure the triangular tiling antiprism does have some regiment members besides the 3 I listed, though. I just need to figure out what they are.

I was not talking about the antiprism. I was talking about this one from the new ones list:

polychoronlover wrote:x4o3o3x4/3*a *b3d (trigonal cupolivert)


And agreed, just make a new one, with a new numbering (I'd probably be willing to help, at least with some of the simplaer regiments).

Indeed, that regiment (the afdec-type) should have a lot more than 274 (and at least that many fissaries). One thing I find interesting is, looking at hedrondude's polyteron spreadsheet that it seems all the nit members either have icoes, rathoes, gicoes, or no ico member at all (and the same goes for the sart regiment). There is not a single one with, say, shahohs as cells. I wonder why this is...

I've also been thinking of that spreadsheet, and noticed that one regiment had most of its members not listed (it was skatbacadint IIRC). I spent some time looking at those, even came up with some possible names for some of them. Also, I started looking more at 6D ones, especially the simpler ones, and coming up with names for them.

Oh, I had forgotten about that one! I was never 100% sure that that was even a valid uniform honeycomb, but the verf doesn't seem to be cut from a larger verf, so the vertices probably don't coincide, so probably nothing coincides... and if that's true then this is valid, and its regiment probably has 79 members just like the Stut Phiddix regiment.

I've been thinking of a plan for my new list of uniform honeycombs. Here is what I have so far:
Code: Select all
chon regiment members w/ A(3) or C(3) verfs
octet regiment members w/ C(3) verfs
tich regiment
tatoh regiment
quitch regiment
rich regiment members w/ C(2)*A(1) or A(1)^3 verfs
srich regiment members w/ A(1)^2 verfs
wavicoca regiment members w/ A(1)^2 verfs
o3x4o~x4/3*b (wavicac) regiment
batch
grich, gratoh, cuteca, o3x4x~x4/3*b, gaqrich, gaqrahch, caquiteca
otch, cutpica, gactipeca, x3x4x~x4/3*b, x4x3x3x4/3*a *b3d, x4/3x4x3/2x3*a *a~c *b4d, gaquapech, quequapech, caquitpica, gacquitpica
prich regiment
quiprich regiment
gepdica regiment
gapdica regiment
x3x4o~x4/3*b regiment
x4x3o3x4/3*a *b3d regiment
chon regiment members w/ A(2) verfs
batatoh regiment
'gotactictosquath' regiment
ratoh regiment
rich regiment members w/ C(2) verfs
gacoco regiment members w/ C(2) verfs
srich regiment members w/ A(1) verfs
skivpacoca regiment
wavicoca regiment members w/ A(1) verfs
x4o3x3x4/3*a *b3d regiment
rich regiment members w/ A(1)^2 verfs
gacoco regiment members w/ A(1)^2 verfs
octet regiment members w/ A(3) verfs
x4o3o3x4/3*a *b3d regiment members
prismatics and their regiments
prisms
regiment members of prisms
other slabs and their regiments
gyrates and elongates

I have some ideas for names:

polychoronlover wrote:o3x4x~x4/3*b

Possible name: Dacta (dicubatitruncated apeiratic honeycomb)

polychoronlover wrote:x3x4x~x4/3*b

Possible name: Dactapa (dicubiatitruncated prismato-apeiratic honeybomc)

polychoronlover wrote:x4x3x3x4/3*a *b3d

Possible name: dicroch (dicubatirhombated cubihexagonal honeycomb)

polychoronlover wrote:x4/3x4x3/2x3*a *a~c *b4d

wait, this one contains x3/2x and is degenerate. Not sure what you meant to write here...

polychoronlover wrote:x3x4o~x4/3*b

Possible name: Sacpaca (Small cubatiprismatocubatiapeiratic honeycomb)

polychoronlover wrote:x4x3o3x4/3*a *b3d

Possible name: Dichac (dicubatihexacubatic honeycomb)

polychoronlover wrote:'gotactictosquath'

Possible shorter name: Getdoca (great tetradicubatiapeiratic honeycomb)

polychoronlover wrote:x4o3x3x4/3*a *b3d

Possible name: Skivcadach (small skewverted cubatiapeiroducubatic honeycomb)

polychoronlover wrote:x4o3o3x4/3*a *b3d

Possible name: Stut Cadoca (small tritrigonary cubatidicuubatiapeiratic honeycomb)

Feel free to adopt some of these names. Or none at all. I'm just giving ideas.

Code: Select all
          _o_
      _3-  |  -4_
   o<      3      >o
      -3_  |  4/3
          -o-

First of all: the linearisation symbol of the above symmetry group you gave as "o4o3o3o4/3*a *b3d" is wrong, as the letter "d" likewise isn't a real node, rather it is a virtaul one too, which re-reffers to the d-th so far already provided real node from the left. Accordingly it ought be prefixed by an asterisk as well. So you'd write rather "o4o3o3o4/3*a *b3*d".

But you could try a different linearisation here as well, cutting open at a threefold node (instead of a normal twofold one) and you'd get e.g. the simpler symbol "o3o3o4/3o4*a3*c" instead.

Next I looked through your according decoration cases.
  • x3x3x4/3x4*a3*c - dicroch = dicubatirhombated cubihexagonal HC, cells are: ^ girco, <| hexat, v quitco, |> cotco
  • o3x3x4/3x4*a3*c - ???, cells are: ^ sirco, <| that, v quitco, |> gocco
  • x3o3x4/3x4*a3*c - dichac = dicubatihexacubatic HC, cells are: ^ tic, <| that, v quith, |> cotco
  • x3x3o4/3x4*a3*c - skivcadach = small skewverted cubatiapeiroducubatic HC, cells are: ^ girco, <| that, v querco, |> socco
  • o3o3x4/3x4*a3*c - stut cadoca = small tritrigonary cubatidicuubatiapeiratic HC, cells are: ^ cube, <| trat, v quith, |> gocco
  • x3o3o4/3x4*a3*c - ???, cells are: ^ tic, <| trat, v cube, |> socco
(Here the symbols ^, <|, v, and |> refer to the accordingly shaped subdiagram. - All other decorations would use some Grünbaumian figure either as cell or as verf.)

You overlooked the "???" cases? At least the according namings are missing.

He was only listing regiment colonels. So, I didn't bother with names for the ones with non-convex verf either.

I'll give some ideas for the other ones here:

i think you have x3x3o4/3x4*a3*c and o3x3x4/3x4*a3*c wrong - the one polychoronlover listed was x4o3x3x4/3*a *b3d, which would be o3x3x4/3x4*a3*c, the one I called Skivcadach. The other one, being its conjugate, shouuld be called Gikkivcadach, switching that "small" for "great".

As for x3o3o4/3x4*a3*c, that one is just Stut Cadoca's conjugate and would be Getit cadoca (again with a "great" instead of "small").
