Small disnub pentishexacosidishexacosichoron

The small disnub pentishexacosidishexacosichoron, or sadsapoxdex, is a nonconvex uniform polychoron that consists of 1200 great icosahedra (some of which lie in the same hyperplanes, forming 600 small retrosnub disoctahedra), 600 icosahedra, 4800 cuboctahedra (forming 2400 compounds of two), 600 small rhombidodecahedra, 600 truncated icosahedra, 600 rhombidodecadodecahedra, and 600 small icosicosidodecahedra.

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

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

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