Great prismatodecachoron

The great prismatodecachoron, or gippid, also commonly called the omnitruncated 5-cell, is a convex uniform polychoron that consists of 20 hexagonal prisms and 10 truncated octahedra. 2 hexagonal prisms and 2 truncated octahedra join at each vertex. It is the omnitruncate of the A4 family of uniform polychora.
