Bigyroprismatic transitional didecafold icosidodecaswirlchoron

The 1-pentadodecahedral swirlprism is an isogonal polychoron, formed as a convex hull of five hexacosichora. It consists of 120 pentagonal biantiprisms and 1200 phyllic disphenoids of two kinds. 3 pentagonal biantiprisms and 8 phyllic disphenoids join at each vertex.

It can be constructed as a subsymmetrical faceting of the rectified hecatonicosachoron.
