Great disnub prismatodisnub trishexacosidishexacosichoron

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

Two icosahedra (two compounds), eight cuboctahedra (eight compounds), five truncated great icosahedra, five rhombidodecadodecahedra, five great icosicosidodecahedra, and five triangular prisms join at each vertex.

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