Great disnub snub prismatosnub pentishecatonicosipentishexacosichoron

The great disnub snub prismatosnub pentishecatonicosipentishexacosichoron, or gidsospas phipix, is a nonconvex uniform polychoron that consists of 600 icosahedra, 4800 cuboctahedra (falling into pairs in the same hyperplanes, forming 2400 compounds of two), 600 rhombidodecadodecahedra, 600 truncated great icosahedra, 1200 great ditrigonal dodecicosidodecahedra (forming 600 compounds of two), 3600 pentagonal prisms, and 3000 truncated tetrahedra (600 of which form 120 truncated chiricosahedra).

One icosahedron, eight cuboctahedra (eight compounds), five rhombidodecadodecahedra, five truncated great icosahedra, five great ditrigonal dodecicosidodecahedra (ten compounds), five pentagonal prisms, and five truncated tetrahedra (one compound and four single) join at each vertex.

It can be obtained as the blend of 5 great dipentary hexacosiprismatodishecatonicosachora and 5 great dipentary hecatonicosidishexacosidishecatonicosachora. 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.
