Small spinoretrosnub snub prismatosnub tetrishexacosipentishecatonicosachoron

The small spinoretrosnub snub prismatosnub tetrishexacosipentishecatonicosachoron, or snarsis pastuxphi, is a nonconvex uniform polychoron that consists of 600 small stellated dodecahedra, 600 icosahedra and 600 great dodecahedra (some of which lie in the same hyperplanes, forming 600 compounds of one of each), 2400 octahemioctahedra and 2400 cubohemioctahedra (forming 2400 compounds of one of each), 600 cuboctahedra (forming 120 antirhombicosicosahedra), 600 truncated icosahedra, 3000 truncated tetrahedra (600 of which form 120 truncated chiricosahedra), and 3600 pentagrammic prisms.

One small stellated dodecahedron, one icosahedron and one great dodecahedron (two compounds), four octahemioctahedra and four cubohemioctahedra (eight compounds), one cuboctahedron (one compound), five truncated icosahedra, five truncated tetrahedra (one compound, four single), and five pentagrammic prisms join at each vertex.

It can be obtained as the blend of 5 small dipentary hecatonicosidishexacosichora and 5 small capped dipentary prismatohexacositrishecatonicosachora. In the process, some of the octahemioctahedron and cubohemioctahedron cells blend out.

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