Great invertifrustary tetrishecatonicosihexacosichoron

The great invertifrustary tetrishecatonicosihexacosichoron, or gifuthix, is a nonconvex uniform polychoron that consists of 120 dodecadodecahedra, 600 octahedra, 120 great ditrigonal dodecicosidodecahedra, 120 small ditrigonal dodecicosidodecahedra, and 120 icosidodecatruncated icosidodecahedra. One dodecadodecahedron, one octahedron, two great ditrigonal dodecicosidodecahedra, two small ditrigonal dodecicosidodecahedra, and four icosidodecatruncated icosidodecahedra join at each vertex.

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