Octacontafold icosidodecaswirlchoron

The octacontafold icosidodecaswirlchoron is an isogonal polychoron with 960 pentagonal gyroprisms, 9600 phyllic disphenoids of two kinds, and 2400 vertices. 4 pentagonal gyroprisms and 16 phyllic disphenoids join at each vertex. It is the twentieth in an infinite family of isogonal icosidodecahedral swirlchora.
