The small retrofrustary prismatodisicositetrachoron, or sirfipdi, is a nonconvex uniform polychoron that consists of 24 quasirhombicuboctahedra, 24 small rhombicuboctahedra, and 96 hexagonal prisms. Two quasirhombicuboctahedra, two small rhombicuboctahedra, and four hexagonal prisms join at each vertex.
