Small disnub snub prismatodisnub tetrishexacosipentishecatonicosachoron

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

One great icosahedron, one great dodecahedron, eight cuboctahedra (eight compounds), five rhombidodecadodecahedra, five small icosicosidodecahedra, 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 hecatonicosihexacosidishecatonicosihexacosichora.

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