Icositetrafold octaswirlchoron

The icositetrafold octaswirlchoron is an isogonal polychoron with 192 triangular antiprisms, 288 rhombic disphenoids and 144 vertices. It is the sixth in an infinite family of isogonal octahedral swirlchora.

The ratio between the longest and shortest edges is 1:$\sqrt{12+6√2+4√9+6√2}$/2 ≈ 1:3.05006.
