Octacontafold icosaswirlchoron

The octacontafold icosaswirlchoron is an isogonal polychoron with 2400 rhombic disphenoids, 9600 phyllic disphenoids of two kinds, and 960 vertices. 10 rhombic and 40 phyllic disphenoids join at each vertex. It is the eighth in an infinite family of isogonal icosahedral swirlchora.
