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.

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

Vertex coordinates
Its vertices are the same as those of its regiment colonel, the disicositetratruncated disicositetrachoron.
