Great snubspinosnub prismatodisnub dishexacosichoron

The great snubspinosnub prismatodisnub dishexacosichoron, or sosenspidsadex, is a nonconvex uniform polychoron that consists of 600 icosahedra, 2400 cuboctahedra and 2400 cubohemioctahedra (falling into pairs in the same hyperplanes, forming 2400 compounds of one of each), 600 octahemioctahedra (forming 120 icosidisicosahedra), 600 rhombicosahedra, and 6000 triangular prisms.

One icosahedron, four cuboctahedra and four cubohemioctahedra (eight compounds), one octahemioctahedron (one compound), five rhombicosahedra, and five triangular prisms join at each vertex.

It can be obtained as the blend of 5 great dipentary prismatohexacosihecatonicosachora and 5 great dipentary hexacosihecatonicosachora. 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 great diretrosnub disnub decahecatonicosadishexacosichoron.
