Snub tetrahedral alterprism

The snub tetrahedral alterprism or snita is a convex isogonal polychoron that consists of 2 snub tetrahedra, 8 triangular antipodiums, 6 rhombic disphenoids, 12 phyllic disphenoids and 24 irregular tetrahedra. However, it cannot be made uniform.

Vertex coordinates
The vertices of a snub tetrahedral alterprism, assuming that the edge length differences are minimized, centered at the origin, are given by the cyclic permutations and even sign changes excluding the last coordinate of:
 * ±($\sqrt{5}$/10, $\sqrt{5}$/5, $\sqrt{110+30√13}$/20, $\sqrt{5}$/10).
