Small stelloctagonal cubiexpandiduoprism

The small stelloctagonal cubiexpandiduoprism, or sisocaxdip, is a nonconvex scaliform polychoron that consists of 32 cubes forming 16 compounds of 2, 64 further cubes, and 16 blends of 5 octagonal prisms. 6 cubes and 4 blends join at each vertex.

It is constructed as a blend of 2 snipto and 2 caco, or alternatively 4 snipto and 4 sodip. It has the same symmetry as the octagonal duoprism.
