Great rhombic trisicositetrachoron

The great rhombic trisicositetrachoron, or girti, is a nonconvex uniform polychoron that consists of 24 great rhombihexahedra, 24 cuboctatruncated cuboctahedra, and 24 great rhombicuboctahedra. One great rhombihexahedron, two cuboctatruncated cuboctahedra, and two great rhombicuboctahedra join at each vertex.
