Hexafold pyritocuboctaswirlchoron

The hexafold pyritocubiswirlchoron is an isogonal polychoron with 48 triangular antiprisms, 288 phyllic disphenoids of two kinds, and 72 vertices. 4 triangular antiprisms and 16 phyllic disphenoids join at each vertex. It is the first in an infinite family of isogonal pyritohedral cuboctahedral swirlchora.

The ratio between the longest and shortest edges is 1:$$\frac{\sqrt{18+6\sqrt6}}{3}$$ ≈ 1:1.90604.
