Hexadecafold octaswirlchoron

The hexadecafold octaswirlchoron is an isogonal polychoron with 192 tetragonal disphenoids, 384 phyllic disphenoids and 96 vertices. 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.
