Triangular-hexagonal triswirlprism

The triangular-hexagonal triswirlprism is a convex isogonal polychoron that consists of 9 hexagonal antiprisms, 18 triangular antiprisms, and 108 phyllic disphenoids of two kinds. 2 hexagonal antiprisms, 2 triangular antiprisms, and 8 phyllic disphenoids join at each vertex. It can be obtained as a subsymmetrical faceting of the enneagonal-octadecagonal duoprism.
