Snub tetracontoctachoric antiprism

The snub tetracontoctachoric antiprism or snocap, also commonly called the omninsub icositetrachoric antiprism, is a convex isogonal polyteron obtained through the process of alternating the great prismatotetracontoctachoric prism. However, it cannot be made uniform.

Using the ratio method, the lowest possible ratio between the longest and shortest edges is 1:$\sqrt{4+2√2√2-2}$/2 ≈ 1:1.20627.
