The small spinoprismatohecatonicosihecatonicosachoron, or snaphihy, is a nonconvex uniform polychoron that consists of 120 great stellated dodecahedra, 720 pentagrammic prisms, and 120 rhombicosahedra. One great stellated dodecahedron, three pentagrammic prisms, and three rhombicosahedra join at each vertex.
