Blended tetracontoctasnub distetracontoctachoron

The blended tetracontoctasnub distetracontoctachoron or becsadic is a nonconvex scaliform polychoron that consists of 96 regular tetrahedra forming 48 stellae octangulae, 288 more tetrahedra, and 48 blends of 4 truncated cubes. 1+3 tetrahedra and 6 blends of 4 truncated cubes join at each vertex.

It can be constructed as a blend of 24 truncated tesseracts, grouping into 6 core full-symmetric truncated tesseracts and 18 sub-symmetric ones, in the same way as the blend of 24 small disprismatotesseractihexadecachora. Its vertex figure is in turn a blend of 1+3 vertex figures of the truncated tesseract. It has tetracontoctachoric symmetry.
