Small disnub snub prismatodisnub pentishecatonicositetrishexacosichoron

The small disnub snub prismatodisnub pentishecatonicositetrishexacosichoron, or sidsospid sphitux, is a nonconvex uniform polychoron that consists of 600 great icosahedra, 4800 cuboctahedra (some of which lie in the same hyperplanes, forming 2400 compounds of two), 600 rhombidodecadodecahedra, 600 small ditrigonal dodecicosidodecahedra, 600 truncated icosahedra, 6000 triangular prisms, and 3000 truncated tetrahedra (600 of which form 120 truncated chiricosahedra).

One great icosahedron, eight cuboctahedra (eight compounds), five rhombidodecadodecahedra, five small ditrigonal dodecicosidodecahedra, five truncated icosahedra, five triangular prisms, and five truncated tetrahedra (one compound and four single) join at each vertex.

It can be obtained as the blend of 5 small dipentary prismatohexacosihecatonicosachora and 5 small dipentary hecatonicosidishexacosidishecatonicosachora.

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