Small dispinosnub snub prismatodisnub trishexacosipentishecatonicosachoron

The small dispinosnub snub prismatodisnub trishexacosipentishecatonicosachoron, or sadinsospid stixophi, is a nonconvex uniform polychoron that consists of 600 great icosahedra, 600 icosahedra, 4800 cubohemioctahedra (some of which lie in the same hyperplanes, forming 2400 compounds of two), 600 rhombicosahedra, 3000 truncated tetrahedra (600 of which form 120 truncated chiricosahedra), and 6000 triangular prisms.

One great icosahedron, one icosahedron, eight cubohemioctahedra (eight compounds), five rhombicosahedra, five truncated tetrahedra (one compound, four single), and five triangular prisms join at each vertex.

It can be obtained as the blend of 5 small dipentary hexacosihecatonicosachora and 5 small dipentary prismatodishexacosidishecatonicosachora. In the process, some of the cubohemioctahedron cells blend out.

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