Small snubspinosnub prismatosnubdisnub tetrishexacosichoron

The small snubspinosnub prismatosnubdisnub tetrishexacosichoron, or sosenspisidstux, is a nonconvex uniform polychoron that consists of 600 great icosahedra and 600 small stellated dodecahedra (some of which lie in the same hyperplanes, forming 600 compounds of one of each), 600 great dodecahedra, 2400 cuboctahedra and 2400 cubohemioctahedra (forming 2400 compounds of one of each), 600 octahemioctahedra (forming 120 icosidisicosahedra), 600 truncated icosahedra, 3600 pentagrammic prisms, and 6000 triangular prisms.

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

It can be obtained as the blend of 5 small dipentary prismatohexacosihecatonicosachora and 5 small capped dipentary prismatohexacositrishecatonicosachora. 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.
