Great dispinosnub prismatosnubdisnub tetrishexacosichoron

The great dispinosnub prismatosnubdisnub tetrishexacosichoron, or gednasposidstux, is a nonconvex uniform polychoron that consists of 600 great icosahedra, 600 great dodecahedra, 4800 cubohemioctahedra (falling into pairs in the same hyperplanes, forming 2400 compounds of two), 1200 great dodecicosahedra (forming 600 compounds of two), 3600 pentagonal prisms, and 6000 triangular prisms.

One great icosahedron, one great dodecahedron, eight cubohemioctahedra (eight compounds), ten great dodecicosahedra (ten compounds), five pentagonal prisms, and five triangular prisms join at each vertex.

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