Thyridocisblended disnub triacontadiadisoctachoron

The thyridocisblended disnub triacontadiadisoctachoron, or yecbid stedo, is a nonconvex uniform polychoron that consists of 8 great icosahedra, 8 icosahedra, 192 tetrahedra, 96+32+32 octahedra, 32 tetrahemihexahedra, 16 octahemioctahedra, and 16 cubohemioctahedra. One great icosahedron, one icosahedron, eight tetrahedra, ten octahedra, two tetrahemihexahedra, two octahemioctahedra and two cubohemioctahedra join at each vertex.

It can be obtained as the blend of a snub hexecontatetrasnub-snub disoctachoron and 4 hexadecaoctadishemioctachora. In the process, some of the octahedron cells blend out.

Vertex coordinates
Its vertices are the same as those of its regiment colonel, the disnub disicositetrachoron.
