Small snubspinosnub prismatosnub dishexacositrishexacosichoron

The small snubspinosnub prismatosnub dishexacositrishexacosichoron, or sosanspos dextix, is a nonconvex uniform polychoron that consists of 600 great icosahedra, 600 great dodecahedra, 2400 cuboctahedra and 2400 cubohemioctahedra (some of which lie in the same hyperplanes, forming 2400 compounds of one of each), 600 octahemioctahedra (forming 120 icosidisicosahedra), 600 small ditrigonal dodecicosidodecahedra, 600 small rhombidodecahedra, 600 truncated icosahedra, and 3600 pentagrammic prisms.

One great icosahedron, one great dodecahedron, four cuboctahedra and four cubohemioctahedra (eight compounds), one octahemioctahedron (one compound), five small ditrigonal dodecicosidodecahedra, five small rhombidodecahedra, five truncated icosahedra, and five pentagrammic prisms join at each vertex.

It can be obtained as the blend of 5 small dipentary hexacosiprismatodishecatonicosachora and 5 small spinobased dipentary hexacositrishecatonicosachora. In the process, some of the cuboctahedron and cubohemioctahedron cells blend out.

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