Great dipentary hexacositrishecatonicosihexacosichoron

The great dipentary hexacositrishecatonicosihexacosichoron, or gidpixthix, is a nonconvex uniform polychoron that consists of 120 great dodecahedra, 600 truncated tetrahedra, 120 rhombidodecadodecahedra, 600 cubohemioctahedra, and 120 great dodecicosidodecahedra. One great dodecahedron, five truncated tetrahedra, five rhombidodecadodecahedra, five cubohemioctahedra, and five great dodecicosidodecahedra join at each vertex.

Vertex coordinates
Its vertices are the same as those of its regiment colonel, the great dipentary trishecatonicosachoron.
