The retrofrustary hexacositrishecatonicosachoron, or raffixthi, is a nonconvex uniform polychoron that consists of 600 octahedra, 120 dodecadodecahedra, 120 small dodecicosidodecahedra, and 120 small ditrigonal dodecicosidodecahedra. 1 octahedron, 1 dodecadodecahedron, 2 small dodecicosidodecahedra, and 2 small ditrigonal dodecicosidodecahedra join at each vertex.
Vertex coordinates[edit | edit source]
Its vertices are the same as those of its regiment colonel, the antifrustary hexacositrishecatonicosachoron.
