The **great spinoprismatotesseractioctachoron**, or **gnipto**, is a nonconvex uniform polychoron that consists of 8 great rhombihexahedra and 32 cubes. Three great rhombihexahedra and four cubes join at each vertex.

It can be constructed as a blend of six square-octagrammic duoprisms. In the process some of the cubes blend out, while the octagrammic prisms blend into great rhombihexahedra.
