Icosafold icosaswirlchoron

The icosafold icosaswirlchoron is an isogonal polychoron with 600 tetragonal disphenoids, 1200 phyllic disphenoids, and 240 vertices. 10 tetragonal and 20 phyllic disphenoids join at each vertex.

It is the second in an infinite family of isogonal icosahedral swirlchora and one of several polychora formed as the hull of various combinations of 2 hexacosichora.
