Great invertifrustary dishexacositetrishecatonicosachoron

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

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