Great retrofrustary hexacositetrishecatonicosachoron

The great retrofrustary hexacositetrishecatonicosachoron, or girfxuthi, is a nonconvex uniform polychoron that consists of 120 quasirhombicosidodecahedra, 120 great dodecicosahedra, 120 small ditrigonal dodecicosidodecahedra, 120 quasitruncated dodecadodecahedra, and 600 truncated octahedra. Two quasirhombicosidodecahedra, two great dodecicosahedra, two small ditrigonal dodecicosidodecahedra, four quasitruncated dodecadodecahedra, and four truncated octahedra join at each vertex.

Vertex coordinates
Its vertices are the same as those of its regiment colonel, the antifrustary hexacositrishecatonicosachoron.
