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 four quasitruncated cuboctahedral prisms. In the process, their cube cells blend out and their octagrammic prism cells blend into great rhombihexahedra.
