IncMats Website Update

[Marek14]

Just 2 months later the next update of my IncMats website is up already!

2019 / 6 / 22
- added an own page on ridge facetings as well as several according sub-pages
- added an own page on lace simplices, listing all the easiest cases each
- added a section on the Dehn-Summerville equations for simplicial polytopes
- several broken links, esp. on the pages for hyperbolic tilings and to pics of polyterons, now got fixed
- exactly 50 new incmats files as well as nearly 150 additional incidence matrices, many of them for various segmentotera, thus summing up to the following totals:

Total count of actually available polytopes: 3448
Total count of contained incidence matrices: 8256

Speaking of hyperbolic tilings, I made some new hi-def images of some, thanks to new HyperRogue features that allow for displaying of general Archimedean tilings. If you want, we could update their page

Next IncMats website update got uploaded.

Changes 2019 / 11 / 23:

- completed the list of all possible up to 5D lace simplices, which use links marked 2 or 3 only
- further downloadable excel spreadsheets, eg. in order to calculate the circumradius of lace prisms and of trigonics respectively
- several new uniform compounds, some with ex components:
  spohi (5) and sody (10), kepisna (6) and pedisna (12), kidisna (10) and ditusna (20);
  others with ico components: kitapna (4) and bitapna (8), kitefa (6) and bitefa (12)
- added a section on the Coxeter-Moser polytopes, a.k.a. regular maps
- even more broken links, esp. to pics of polyterons, now got fixed
- cross-linking to Nan Ma's page on regular stars
- nearly 60 new incmats files as well as nearly 150 additional incidence matrices, many of them in 5D


(Sorry @Marek14 for not having replied to you so far. I did get your provided pics. But still hadn't enough time to exchange them one by one.)

Hi,

just want to inform you about the recent update of my incmats website http://bendwavy.org/klitzing/home.htm .
(In case don't miss to hit the reload button to get the newed pages and not those from your cache...)

Some of the recent changes:

- many more 4D uniform compounds listed, even started to collect 7D & 8D compounds
- also extended to 7D combinations of extrusions and taperings, cf. |,>,O devices
- the notion of alterprisms is being added (thereby elaborating various further scaliform examples),
  as well as introducing according acronym shortenings (X-al-X becoming now simply X-a)
- some more polychora investigated wrt. EKF constructions therefrom
- hidicau pretasto, a further outstanding CRF has been found after a long time of silence in this resort
- section on the hypersine function for hypersolid corner angles
- cross-linking to a new polytopewiki
- over 80 new incmats files as well as 160 additional incidence matrices

Have a look!

(In case don't miss to hit the reload button to get the newed pages and not those from your cache...)

Some of the recent changes:

- added a page on isogonal polytopes with quite a lot of according stuff from a current research project
- noticed that firp in fact is a 4D cuploid and found a further such: co retro-cuploid
- found a new scaliform honeycomb with vertex configuration 5 Y4 + 3 T + 3 Q3 + 1 T3
- continued cross-linking of the still quite fast growing polytopewiki
- started to collect some twins
- major xhtml-reworking: erasing lots of html-allowed, but not well-defined xml
- finally providing OBSAs for the polygons as well
- started to provide OBSAs for hyperbolics as well
- started to collect compounds of euclidean tilings as well
- nearly 200 new incmats files as well as more than 250 additional incidence matrices

Have a look!

Me and Zeno have been collecting my tilings at https://zenorogue.github.io/tes-catalog/ . I started in tilings many years ago by researching uniform (a,a,a,b) tilings, and now I have finished the classification of 2-uniform (a,a,a,b) as well
