Thank you for pointing out the copy-n-paste error with bicypdrahi - which indeed lasted for quite long already, undiscovered.

The point about saddid and sidditdid well is correct, as they indeed are different abstract polytopes, i.e. having different 0-1-matrices, while their symmetry-type incidence matrices no longer care about the different hole types involved. Thus in a quite limiting reading of "twins" those well could be considered such. However those still are far away from the very concern to enlist known pairs of polytopes, which are "largely different" and still have the same face vectors. Thence having largely different incidence matrices - even when considered with respect to symmetry types only, and this not only because of considering different (sub)symmetry representations, orientations or gyrations, would rather be the main concern.

Just want to announce that the IncMat website https://bendwavy.org/klitzing/home.htm has got a further update!
Go and check out! - (You might want to hit [F5] if the cache displays the old content still.)

Version Changes
2023 / 4 / 8

- provided summarized face vectors, both for individual incmat files as well as within some index files
- further polytopal families in dimensional analogs
- emphasizing the matching condition and providing side lengths for all Schwarz triangles too
- some further hyperbolic pentacombs
- further 5D A,B,B-trigonics
- para- and hypercompact Gossetics (up to rank 10)
- truncation and rectification being applied onto abstract Grünbaum-Coxeter polytopes: the 11-cell and the 57-cell
- inserting back-links from individual (Wythoffian) polytope file into dimensional listings
- description and examples of Waterman polytopes
- nearly 90 new incmats files, more than 100 new incidence matrices

That reminds me of these sites I found in a search for degenerate CRF polyhedra:

Website updates! -> https://bendwavy.org/klitzing/home.htm
- expanded to 4D Waterman polytopes
- major rewrite and huge expansion of complex polytopes with lots of examples
- nearly 120 new incmats files, more than 360 new individual incidence matrices

next update of my IncMats website https://bendwavy.org/klitzing/home.htm

  • ambification further elaborated as well as reverse linked in the individual polytope files
  • some more starry, laminate, and other hyperbolics
  • some more partially snubbed polypeta
  • explanation of sefa derivation process
  • bitruncated simplices and bitruncated hypercubes added to the analog listings
  • rhombated and quasirhombated hypercubes added to the analog listings as well
  • expansion of deltahedra et al. page, now listing homotopal CRFs up to 6D
  • adding the (abstract) "tomotope" as well as its truncation and rectification
  • T. Ruen's "mystic" x3o6o|x3o substructure of hex
  • sadly the previous external pic-refs from http://bulatov.org/polyhedra/ seemingly no longer get resolved any longer,
    accordingly these had to be replaced with still working ones from https://en.wikipedia.org/wiki/ instead
  • more than 130 new incmats files, nearly 240 new incidence matrices
