Small tetrisicositetrachoron

The small tetrisicositetrachoron, or suti, is a nonconvex uniform polychoron that consists of 24 truncated octahedra, 24 quasitruncated hexahedra, 24 small rhombicuboctahedra, and 24 quasitruncated cuboctahedra. 1 quasitruncated hexahedron, 1 truncated octahedron, 1 small rhombicuboctahedron, and 2 quasitruncated cuboctahedra join at each vertex.

The small tetrisicositetrachoron contains the vertices of a tesseractihexadecaquasitruncated prismatotesseractihexadecachoron.
