Hexadecafold octaswirlchoron

The hexadecafold octaswirlchoron is an isogonal polychoron with 192 tetragonal disphenoids, 384 phyllic disphenoids, and 96 vertices. 8 tetragonal and 16 phyllic disphenoids join at each vertex. It is the fourth in an infinite family of isogonal octahedral swirlchora.

The ratio between the longest and shortest edges is 1:$$\frac{\sqrt{8+2\sqrt2+4\sqrt{2+\sqrt2}}}{2}$$ ≈ 1:2.13421.
