Great retroinverted ditetrahedronary hecatonicosiprismatohecatonicosachoron

The great retroinverted ditetrahedronary hecatonicosiprismatohecatonicosachoron, or gridathiphi, is a nonconvex uniform polychoron that consists of 120 dodecahedra, 720 pentagonal prisms, and 120 rhombicosahedra. Four dodecahedra, twelve pentagonal prisms, and twelve rhombicosahedra join at each vertex.

Vertex coordinates
Its vertices are the same as those of its regiment colonel, the ditetrahedronary dishecatonicosachoron.
