Snub decachoric antiprism

The snub decachoric antiprism or snadap, also commonly called the omnisnub pentachoric antiprism, is a convex isogonal polyteron that consists of 2 snub decachora, 10 snub tetrahedral antiprisms, 20 digonal-triangular duoantiprisms, and 120 phyllic disphenoidal pyramids. 1 snub decachoron, 2 snub tetrahedral antiprisms, 2 digonal-triangular duoantiprisms, and phyllic disphenoidal pyramids join at each vertex. It can be obtained through the process of alternating the great prismatodecachoric prism. However, it cannot be made uniform.

Using the ratio method, the lowest possible ratio between the longest and shortest edges is $$\sqrt{\frac{3+\sqrt2}{3}}$$ ≈ 1.21301.
