Small disnub tetrishexacositrishexacosichoron

The small disnub tetrishexacositrishexacosichoron, or sadstuxtex, is a nonconvex uniform polychoron that consists of 1200 great icosahedra (some of which lie in the same hyperplanes, forming 600 small retrosnub disoctahedra), 1200 icosahedra (forming 600 snub disoctahedra), 4800 cuboctahedra (forming 2400 compounds of two), 600 small rhombidodecahedra, 600 rhombicosahedra, and 600 small dodecicosahedra.

Two great icosahedra (two compounds), two icosahedra (two compounds), eight cuboctahedra (eight compounds), five small rhombidodecahedra, five rhombicosahedra, and five small dodecicosahedra join at each vertex.

It can be obtained as the blend of 5 small dipentary hecatonicosihexacosidishecatonicosachora and 5 small based dipentary tetrishecatonicosihexacosichora.

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