Snub disicositetrachoric antiprism

The snub disicositetrachoric antiprism or sadiap, also commonly called the snub rhombatohexadecachoric antiprism or omnisnub demitesseractic antiprism, is a convex isogonal polyteron obtained through the process of alternating the truncated icositetrachoric prism. However, it cannot be made uniform.

Vertex coordinates
The vertices of a snub disicositetrachoric antiprism, assuming that the edge length differences are minimized, centered at the origin, are given by the cyclic permutations excluding the last coordinate of:


 * (0, ±1/2, ±(3+$\sqrt{17}$)/8, ±(7+$\sqrt{17}$)/8, $\sqrt{7+√17}$/8).
