Great disnub prismatosnub heptishexacosichoron

The great disnub prismatosnub heptishexacosichoron, or gudspeshax, is a nonconvex uniform polychoron that consists of 600 small stellated dodecahedra, 600 icosahedra, 4800 cuboctahedra (falling into pairs in the same hyperplanes, forming 2400 compounds of two), 600 rhombidodecadodecahedra, 600 truncated great icosahedra, 600 great dodecicosidodecahedra, 600 great ditrigonal dodecicosidodecahedra and 600 great icosicosidodecahedra (forming 600 compounds of one of each), and 3600 pentagonal prisms.

One small stellated dodecahedron, one icosahedron, eight cuboctahedra (eight compounds), five rhombidodecadodecahedra, five truncated great icosahedra, five great dodecicosidodecahedra, five great ditrigonal dodecicosidodecahedra and five great icosicosidodecahedra (ten compounds), and five pentagonal prisms join at each vertex.

It can be obtained as the blend of 5 great dipentary dishecatonicosihexacosidishecatonicosachora and 5 great dipentary prismatohexacositrishecatonicosachora.

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