Great retrofrustary pentishecatonicosachoron

The great retrofrustary pentishecatonicosachoron, or girfophi, is a nonconvex uniform polychoron that consists of 120 quasirhombicosidodecahedra, 120 great ditrigonal dodecicosidodecahedra, 120 small rhombicosidodecahedra, 120 small ditrigonal dodecicosidodecahedra, and 120 quasitruncated dodecadodecahedra. Two quasirhombicosidodecahedra, two great ditrigonal dodecicosidodecahedra, two small rhombicosidodecahedra, two small ditrigonal dodecicosidodecahedra, and four quasitruncated dodecadodecahedra join at each vertex.

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