The great rhombic disoctachoron, or girdo, is a nonconvex uniform polychoron that consists of 8 quasitruncated hexahedra, 8 great rhombihexahedra, and 32 triangular prisms. 2 of each type of cell join at each vertex.
It can be constructed as a blend of four quasitruncated hexahedral prisms. In the process the octagrammic prisms blend into great rhombihexahedra]]
