Great rhombiprismic tesseractihexadecachoron

The great rhombiprismic tesseractihexadecachoron, or girpith, is a nonconvex uniform polychoron that consists of 16 cubohemioctahedra, 24 octagrammic prisms, and 8 quasitruncated cuboctahedra. One cubohemioctahedron, two octagrammic prisms, and two quasitruncated cuboctahedra join at each vertex.

Vertex coordinates
Its vertices are the same as those of its regiment colonel, the quasiprismatorhombated hexadecachoron.
