Great invertifrustary pentishecatonicosihexacosichoron

The great invertifrustary pentishecatonicosihexacosichoron, or gifophix, is a nonconvex uniform polychoron that consists of 120 dodecadodecahedra, 600 octahedra, 120 quasirhombicosidodecahedra, 120 great ditrigonal dodecicosidodecahedra, 120 small rhombidodecahedra, and 120 quasitruncated dodecadodecahedra. One dodecadodecahedron, one octahedron, two quasirhombicosidodecahedra, two great ditrigonal dodecicosidodecahedra, two small rhombidodecahedra, and four quasitruncated dodecadodecahedra join at each vertex.

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