Great disnub snub prismatodisnub pentishecatonicositetrishexacosichoron

The great disnub snub prismatodisnub pentishecatonicositetrishexacosichoron, or gidsospid sphitux, 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 great ditrigonal dodecicosidodecahedra, 600 truncated great icosahedra, 6000 triangular prisms, and 3000 truncated tetrahedra (600 of which form 120 truncated chiricosahedra).

One icosahedron, eight cuboctahedra (eight compounds), five rhombidodecadodecahedra, five great ditrigonal dodecicosidodecahedra, 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 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.
