Great disnub prismatodisnub dishexacosidishexacosichoron

The great disnub prismatodisnub dishexacosidishexacosichoron, or gadspid sedoxdix, is a nonconvex uniform polychoron that consists of 600 great icosahedra, 1200 regular icosahedra (falling into pairs in the same hyperplanes, forming 600 snub disoctahedra), 4800 cuboctahedra (forming 2400 compounds of two), 600 great rhombidodecahedra, and 6000 triangular prisms.

One great icosahedron, two regular icosahedra (two compounds), eight cuboctahedra (eight compounds), five great rhombidodecahedra, and five triangular prisms join at each vertex.

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

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