Pentagonal double gyroantiprismoid

The pentagonal double gyroantiprismoid is a convex isogonal polychoron and the fourth member of the double gyroantiprismoid family. It consists of 20 pentagonal antiprisms, 50 tetragonal disphenoids, 100 rhombic disphenoids, and 200 sphenoids. 2 pentagonal antiprisms, 2 tetragonal disphenoids, 4 rhombic disphenoids, and 8 sphenoids join at each vertex. However, it cannot be made uniform. It is the second in an infinite family of isogonal pentagonal prismatic swirlchora.
