Digonal-triangular triswirlprism

The digonal-triangular triswirlprism is a convex isogonal polychoron that consists of 6 triangular antiprisms, 9 rhombic disphenoids and 18 phyllic disphenoids obtained as a subsymmetrical faceting of the hexagonal-enneagonal duoprism. It is the simplest nontrivial member of the duoprismatic swirlprisms.
