Small disnub prismatosnub hexishexacosichoron

The small disnub prismatosnub hexishexacosichoron, or sudsposhex, is a nonconvex uniform polychoron that consists of 600 great icosahedra and 600 small stellated dodecahedra (some of which lie in the same hyperplanes, forming 600 compounds of one of each of them), 600 icosahedra, 4800 cuboctahedra (forming 2400 compounds of two), 600 small ditrigonal dodecicosidodecahedra, 600 rhombidodecadodecahedra, 600 small dodecicosidodecahedra, and 3600 pentagrammic prisms.

One great icosahedron and one small stellated dodecahedron (one compound), one icosahedron, eight cuboctahedra (eight compounds), five small ditrigonal dodecicosidodecahedra, five rhombidodecadodecahedra, five small dodecicosidodecahedra, and five pentagrammic prisms join at each vertex.

It can be obtained as the blend of 5 small dipentary hexacosiprismatodishecatonicosachora and 5 small dipentary hexacositetrishecatonicosachora.

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