Snub decachoron

The snub decachoron, or snad, also commonly called the omninsub pentachoron or omnisnub 5-cell, is a convex isogonal polychoron that consists of 10 snub tetrahedra, 20 triangular antiprisms and 60 phyllic disphenoids obtained through the process of alternating the great prismatodecachoron. However, it cannot be made uniform.

Using the ratio method, the lowest possible ratio between the longest and shortest edges is 1:$\sqrt{9+3√2}$/3 ≈ 1:1.21301.

Vertex coordinates
Much simpler coordinates can be given in five dimensions for an optimized snub decachoron, as all even permutations of:

which has rhombic disphenoids (via the absolute value method), or where the ratio of the largest edge length to the smallest edge length is lowest (via the ratio method).
