Great rhombiprismic disicositetrachoron

The great rhombiprismic disicositetrachoron, or girpdi, is a nonconvex uniform polychoron that consists of 24 great rhombihexahedra, 24 quasitruncated cuboctahedra, and 96 hexagonal prisms. One great rhombihexahedron, two quasitruncated cuboctahedra, and two hexagonal prisms join at each vertex.

It can be constructed as a blend of three great quasidisprismatotesseractihexadecachora. In the process the truncated octahedra blendd out, while the octagrammic prisms blend into great rhombihexahedra.

Vertex coordinates
Its vertices are the same as those of its regiment colonel, the great prismatotrisicositetrachoron.
