Great retrofrustary prismatotetrishecatonicosachoron

The great retrofrustary prismatotetrishecatonicosachoron, or girfupthi, is a nonconvex uniform polychoron that consists of 120 quasirhombicosidodecahedra, 120 great dodecicosahedra, 120 small ditrigonal dodecicosidodecahedra, 120 icosidodecatruncated icosidodecahedra, and 1200 hexagonal prisms. Two quasirhombicosidodecahedra, two great dodecicosahedra, two small ditrigonal dodecicosidodecahedra, four icosidodecatruncated icosidodecahedra, and four hexagonal prisms join at each vertex.

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