Octafold small rhombicuboctaswirlchoron

The octafold small rhombicuboctaswirlchoron is an isogonal polychoron with 48 square gyroprisms, 192 rhombic disphenoids of two kinds, 192 phyllic disphenoids, 384 irregular tetrahedra, and 192 vertices. 2 square gyroprisms, 4 rhombic disphenoids, 4 phyllic disphenoids, and 8 irregular tetrahedra join at each vertex. It is the first in an infinite family of isogonal small rhombicuboctahedral swirlchora.

Using the ratio method, the lowest possible ratio between the longest and shortest edges is 1:$$\frac{\sqrt{12+2\sqrt2}}{2}$$ ≈ 1:1.92538.
