Great dipentary hecatonicosihecatonicosihexacosichoron

The great dipentary hecatonicosihecatonicosihexacosichoron, or gidphihix, is a nonconvex uniform polychoron that consists of 120 icosahedra, 600 truncated tetrahedra, and 120 great dodecicosahedra. One icosahedron, five truncated tetrahedra, and five great dodecicosahedra join at each vertex.

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