Digonal-pentagonal tetraswirlprism

The digonal-pentagonal tetraswirlprism is a convex isogonal polychoron and member of the duoprismatic swirlprism family that consists of 8 pentagonal gyroprisms, 20 rhombic disphenoids, and 120 phyllic disphenoids of three kinds. 2 pentagonal gyroprisms, 2 rhombic disphenoids, and 12 phyllic disphenoids join at each vertex. It can be obtained as a subsymmetrical faceting of the octagonal-icosagonal duoprism.
