Great disnub prismatodisnub pentishexacosichoron

The great disnub prismatodisnub pentishexacosichoron, or gadspid sopex, is a nonconvex uniform polychoron that consists of 600 great icosahedra, 600 icosahedra and 600 great dodecahedra (falling into pairs in the same hyperplanes, forming 600 compounds of one of each), 4800 cuboctahedra (forming 2400 compounds of two), 600 rhombidodecadodecahedra, 600 great dodecicosidodecahedra, and 6000 triangular prisms.

One great icosahedron, one icosahedron and one great dodecahedron (two compounds), eight cuboctahedra (eight compounds), five rhombidodecadodecahedra, five great dodecicosidodecahedra, and five triangular prisms join at each vertex.

It can be obtained as the blend of 5 great dipentary prismatohexacosihecatonicosachora and 5 great dipentary hexacositetrishecatonicosachora.

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