Great great dipentary trishecatonicosachoron

The great great dipentary trishecatonicosachoron, or gigdipthi, is a nonconvex uniform polychoron that consists of 120 great dodecahedra, 120 truncated great icosahedra, and 120 icosidodecadodecahedra. One great dodecahedron, five truncated great icosahedra, and five icosidodecadodecahedra join at each vertex.

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