Snub digonal-triangular prismantiprismoid

The snub digonal-triangular prismantiprismoid is a convex isogonal polychoron and the second member of the truncatoprismantiprismoids that consists of 8 triangular antiprisms of two kinds, 6 tetragonal disphenoids, 6 rhombic disphenoids, 12 phyllic disphenoids and 48 irregular tetrahedra of two kinds obtained from the process of alternating a digonal-triangular truncatoprismantiprismoid. However, it cannot be made uniform.

Using the ratio method, the lowest possible ratio between the longest and shortest edges is 1:a ≈ 1:1.51285, where a is the second-largest real root of 25x6-183x4+339x2-117.
