Great retrosphenoverted trishecatonicosachoron

The great retrosphenoverted trishecatonicosachoron, or grawvathi, is a nonconvex uniform polychoron that consists of 120 truncated icosahedra, 120 icosidodecahedra, and 120 great icosicosidodecahedra. 1 icosidodecahedron, 2 truncated icosahedra, and 2 great icosicosidodecahedra join at each vertex.

Vertex coordinates
Its vertices are the same as those of its regiment colonel, the small sphenoverted ditrigonal trishecatonicosachoron.
