Triangular-pentagonal tetraswirlprism

The triangular-pentagonal tetraswirlprism is a convex isogonal polychoron and member of the duoprismatic swirlprism family that consists of 12 pentagonal gyroprisms, 20 triangular gyroprisms, and 180 phyllic disphenoids of three kinds. 2 pentagonal gyroprisms, 2 triangular gyroprisms, and 12 phyllic disphenoids join at each vertex. It can be obtained as a subsymmetrical faceting of the dodecagonal-icosagonal duoprism.
