The small dipentary prismatotrishecatonicosihexacosichoron, or siddip pathix, is a nonconvex uniform polychoron that consists of 1200 triangular prisms, 600 truncated tetrahedra, 120 rhombidodecadodecahedra, 120 small icosicosidodecahedra, and 120 small dodecicosidodecahedra. Five of each join at each vertex.
