Pentagonal trioantiprism

The pentagonal trioantiprism, or pettap, is a convex isogonal polypeton that consists of 30 pentagonal duoantiprismatic antiprisms and 500 digonal trisphenoids. 6 of each facet type join at each vertex. It can be obtained through the process of alternating the decagonal trioprism. However, it cannot be made uniform.
