Great dispinosnub prismatosnub tetrishexacosichoron

The great dispinosnub prismatosnub tetrishexacosichoron, or gednaspistux, is a nonconvex uniform polychoron that consists of 600 small stellated dodecahedra, 600 great dodecahedra, 4800 cubohemioctahedra (falling into pairs in the same hyperplanes, forming 2400 compounds of two), 600 truncated great icosahedra, 600 rhombicosahedra, and 3600 pentagonal prisms.

One small stellated dodecahedron, one great dodecahedron, eight cubohemioctahedra (eight compounds), five truncated great icosahedra, five rhombicosahedra, and five pentagonal prisms join at each vertex.

It can be obtained as the blend of 5 great dipentary hexacosihecatonicosachora and 5 great capped dipentary prismatohexacositrishecatonicosachora. In the process, some of the cubohemioctahedron cells blend out.

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