Small spinoretrosnub prismatosnub dishexacositetrishexacosichoron

The small spinoretrosnub prismatosnub dishexacositetrishexacosichoron, or snarsip sadixtux, is a nonconvex uniform polychoron that consists of 1200 small stellated dodecahedra (some of which lie in the same hyperplanes, forming 600 pentagrammatic snub pseudodisoctahedra), 600 icosahedra, 2400 octahemioctahedra and 2400 cubohemioctahedra (forming 2400 compounds of one of each), 600 cuboctahedra (forming 120 antirhombicosicosahedra), 600 icosidodecadodecahedra, 600 small dodecicosidodecahedra, 600 small dodecicosahedra, and 3600 pentagrammic prisms.

Two small stellated dodecahedra (two compounds), one icosahedron, four octahemioctahedra and four cubohemioctahedra (eight compounds), one cuboctahedron (one compound), five icosidodecadodecahedra, five small dodecicosidodecahedra, five small dodecicosahedra, and five pentagrammic prisms join at each vertex.

It can be obtained as the blend of 5 small dipentary tetrishecatonicosihexacosichora and 5 small dipentary hecatonicosiprismatohecatonicosihexacosichora. 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.
