Small diretrosnub snub prismatodisnub tetrishexacosipentishecatonicosachoron

The small diretrosnub snub prismatodisnub tetrishexacosipentishecatonicosachoron, or sadersospid stuxphi, is a nonconvex uniform polychoron that consists of 600 small stellated dodecahedra, 600 icosahedra, 4800 octahemioctahedra (some of which lie in the same hyperplanes, forming 2400 compounds of two), 600 icosidodecadodecahedra, 600 small rhombicosidodecahedra, 6000 triangular prisms, and 3000 truncated tetrahedra (600 of which form 120 truncated chiricosahedra).

One small stellated dodecahedron, one icosahedron, eight octahemioctahedra (eight compounds), five icosidodecadodecahedra, five small rhombicosidodecahedra, 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 hecatonicosidishexacosichora and 5 small capped dipentary trishecatonicosiprismatohexacosichora.

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