Great disnub snub prismatodisnub pentishecatonicosipentishexacosichoron

The great disnub snub prismatodisnub pentishecatonicosipentishexacosichoron, or gidsospid sphipix, is a nonconvex uniform polychoron that consists of 600 great icosahedra, 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 truncated great icosahedra, 6000 triangular prisms, and 3000 truncated tetrahedra (600 of which form 120 truncated chiricosahedra).

One great icosahedron, one icosahedron and one great dodecahedron (two compounds), eight cuboctahedra (eight compounds), five rhombidodecadodecahedra, five truncated great icosahedra, five triangular 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 prismatohexacosihecatonicosachora and 5 great dipentary hexacosihecatonicosihexacositrishecatonicosachora. 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.
