Antifrustary hexacosipentishecatonicosachoron

The antifrustary hexacosipentishecatonicosachoron, or afxophi, is a nonconvex uniform polychoron that consists of 120 dodecadodecahedra, 600 octahedra, 120 great rhombidodecahedra, 120 great dodecicosahedra, 120 small rhombicosidodecahedra, and 120 small icosicosidodecahedra. One dodecadodecahedron, one octahedron, two great rhombidodecahedra, two great dodecicosahedra, two small rhombicosidodecahedra, and two small icosicosidodecahedra join at each vertex.

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