Hollow cuboid cupoliprism

The hollow cubic cupoliprism or hocucup is a prismatic scaliform polychoron that consists of 6 stella octangulas (or 12 tetrahedra) and 12 blends of 2 triangular prisms. Each vertex is met by two tetrahedra and four blends of 2 triangular prisms.

This polychoron can be created as a blend of 6 tetrahedral prisms (in the form of 6 digonal antiduoprisms).
