Retroinvertifrustary hexacositetrishecatonicosachoron

The retroinvertifrustary hexacositetrishecatonicosachoron, or rifxuthi, is a nonconvex uniform polychoron that consists of 120 great ditrigonal dodecicosidodecahedra, 120 small rhombicosidodecahedra, 120 small dodecicosahedra, 120 quasitruncated dodecadodecahedra, and 600 truncated octahedra. Two great ditrigonal dodecicosidodecahedra, two small rhombicosidodecahedra, two small dodecicosahedra, four quasitruncated dodecadodecahedra, and four truncated octahedra join at each vertex.

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