Grand invertifrustary pentishecatonicosachoron

The grand invertifrustary pentishecatonicosachoron, or gifophi, is a nonconvex uniform polychoron that consists of 120 quasirhombicosidodecahedra, 120 great dodecicosahedra, 120 small rhombidodecahedra, 120 small icosicosidodecahedra, and 120 icosidodecatruncated icosidodecahedra. Two quasirhombicosidodecahedra, two great dodecicosahedra, two small rhombidodecahedra, two small icosicosidodecahedra, and four icosidodecatruncated icosidodecahedra join at each vertex.

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