Swirlblended tetracontoctasnub distetracontoctachoron

The swirlblended tetracontoctasnub distetracontoctachoron or sebicsadic is a nonconvex scaliform polychoron that consists of 96 regular tetrahedra forming 48 stellae octangulae, 192 more tetrahedra, and 48 blends of 3 truncated cubes. 1+2 tetrahedra and 5 blends of 3 truncated cubes join at each vertex.

It can be constructed as a blend of 18 truncated tesseracts, grouping into 6 core full-symmetric truncated tesseracts and 12 sub-symmetric ones. Its vertex figure is in turn a blend of 1+2 vertex figures of the truncated tesseract.
