Retrofrustary dishecatonicosihexacosichoron

The retrofrustary dishecatonicosihexacosichoron, or rafdohix, is a nonconvex uniform polychoron that consists of 120 small rhombidodecahedra, 120 small dodecicosahedra, and 600 truncated octahedra. Two small rhombidodecahedra, two small dodecicosahedra, and four truncated octahedra join at each vertex.
