Great dispinosnub prismatosnub hexishexacosichoron

The great dispinosnub prismatosnub hexishexacosichoron, or gednaspishax, is a nonconvex uniform polychoron that consists of 600 small stellated dodecahedra, 1200 great dodecahedra (falling into pairs in the same hyperplanes, forming 600 pentagonal retrosnub pseudodisoctahedra), 4800 cubohemioctahedra (forming 2400 compounds of two), 600 rhombidodecadodecahedra, 1200 great dodecicosahedra (forming 600 compounds of two), and 3600 pentagonal prisms.

One small stellated dodecahedron, two great dodecahedra (two compounds), eight cubohemioctahedra (eight compounds), five rhombidodecadodecahedra, ten great dodecicosahedra (ten compounds), and five pentagonal prisms join at each vertex.

It can be obtained as the blend of 5 great capped dipentary tetrishecatonicosihexacosichora and 5 great dipentary hecatonicosiprismatohecatonicosihexacosichora. 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.
