Rectified hendecagonal duoprism

The rectified hendecagonal duoprism or rehendip is a convex isogonal polychoron that consists of 22 rectified hendecagonal prisms and 121 tetragonal disphenoids. 3 rectified hendecagonal duoprisms and 2 tetragonal disphenoids join at each vertex. It can be formed by rectifying the hendecagonal duoprism.

It can also be formed as the convex hull of 2 oppositely oriented semi-uniform hendecagonal duoprisms, where the edges of one hendecagon are $$\frac{1}{\cos\frac{\pi}{11}} ≈ 1.04222$$ times as long as the edges of the other.

The ratio between the longest and shortest edges is 1:$$\frac{2\cos\frac\pi{11}}{\sqrt2}$$ ≈ 1:1.35693.
