11-2 step prism

The 11-2 step prism is a convex isogonal polychoron and a member of the step prism family. It has 44 phyllic disphenoids of four kinds as cells, with 16 joining at each vertex.

It is one of two isogonal polychora with 11 vertices, the other being the 11-3 step prism.

Vertex coordinates
Coordinates for the vertices of an 11-2 step prism inscribed in a hendecagonal duoprism with base lengths a and b are given by: where k is an integer from 0 to 10. If the edge length differences are to be minimized, the ratio of a:b must be equivalent to :$$\sqrt{1-\frac{1}{1+2\cos\frac{\pi}{11}}}$$ ≈ 1:0.79197.
