Hexagonal duoantiprismatic antiprism

The hexagonal duoantiprismatic antiprism is a convex isogonal polyteron that consists of 2 hexagonal duoantiprisms, 24 digonal-hexagonal duoantiprisms and 144 tetragonal disphenoidal pyramids obtained through the process of alternating the dodecagonal duoprismatic prism. However, it cannot be made uniform.

Using the ratio method, the lowest possible ratio between the longest and shortest edges is 1:$$\frac{1+\sqrt3}{2}$$ ≈ 1:1.36603.
