Pentagonal-hexagonal triswirlprism

The pentagonal-hexagonal triswirlprism is a convex isogonal polychoron and member of the duoprismatic swirlprism family that consists of 15 hexagonal antiprisms, 18 pentagonal antiprisms, and 180 phyllic disphenoids of two kinds. 2 hexagonal antiprisms, 2 pentagonal antiprisms, and 8 phyllic disphenoids join at each vertex. It can be obtained as a subsymmetrical faceting of the pentadecagonal-octadecagonal duoprism.
