Great rhombiprismic disoctachoron

The great rhombiprismic disoctachoron, or girpdo, is a nonconvex uniform polychoron that consists of 8 great rhombihexahedra, 8 quasitruncated cuboctahedra, and 32 hexagonal prisms. One great rhombihexahedron, two quasitruncated cuboctahedra, and two hexagonal prisms join at each vertex.

It can be constructed as a blend of a compound of four quasitruncated cuboctahedral prisms.

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