Great disnub pentishexacosidishexacosichoron

The great disnub pentishexacosidishexacosichoron, or gadsapoxdex, is a nonconvex uniform polychoron that consists of 600 great icosahedra, 1200 icosahedra (falling into pairs in the same hyperplanes, forming 600 snub disoctahedra), 4800 cuboctahedra (forming 2400 compounds of two), 600 great rhombidodecahedra, 600 truncated great icosahedra, 600 rhombidodecadodecahedra, and 600 great icosicosidodecahedra.

One great icosahedron, two icosahedra (two compounds), eight cuboctahedra (eight compounds), five great rhombidodecahedra, five truncated great icosahedra, five rhombidodecadodecahedra, and five great icosicosidodecahedra join at each vertex.

It can be obtained as the blend of 5 great dipentary hecatonicosihexacosidishecatonicosachora and 5 great dipentary hexacosidishecatonicosidishecatonicosachora.

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