Great disnub snub pentishecatonicosiheptishexacosichoron

The great disnub snub pentishecatonicosiheptishexacosichoron, or gidsosphiheex, is a nonconvex uniform polychoron that consists of 600 small stellated dodecahedra, 600 icosahedra and 600 great dodecahedra (some of which lie in the same hyperplanes, forming 600 compounds of one of each), 4800 cuboctahedra (forming 2400 compounds of two), 600 rhombidodecadodecahedra, 600 great ditrigonal dodecicosidodecahedra and 600 great icosicosidodecahedra (forming 600 compounds of one of each), 600 great rhombidodecahedra, and 3000 truncated tetrahedra (600 of which form 120 truncated chiricosahedra).

One small stellated dodecahedron, one icosahedron and one great dodecahedron (two compounds), eight cuboctahedra (eight compounds), five rhombidodecadodecahedra, five great ditrigonal dodecicosidodecahedra and five great icosicosidodecahedra (ten compounds), five great rhombidodecahedra, and five truncated tetrahedra (one compound and four single) join at each vertex.

It can be obtained as the blend of 5 great dipentary dishecatonicosihexacosidishecatonicosachora and 5 great dipentary dishecatonicosidishexacosihecatonicosachora. In the process, some of the cuboctahedron cells blend out.

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