Small disnub prismatodisnub trishexacosidishexacosichoron

The small disnub prismatodisnub trishexacosidishexacosichoron, or sadspid staxdix, is a nonconvex uniform polychoron that consists of 1200 great icosahedra (some of which lie in the same hyperplanes, forming 600 small retrosnub disoctahedra), 4800 cuboctahedra (forming 2400 compounds of two), 600 truncated icosahedra, 600 rhombidodecadodecahedra, 600 small icosicosidodecahedra, and 6000 triangular prisms.

Two great icosahedra (two compounds), eight cuboctahedra (eight compounds), five truncated icosahedra, five rhombidodecadodecahedra, five small icosicosidodecahedra, and five triangular prisms join at each vertex.

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

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