Octagonal-hendecagonal duoprismatic prism

The octagonal-hendecagonal duoprismatic prism or ohenip, also known as the octagonal-hendecagonal prismatic duoprism, is a convex uniform duoprism that consists of 2 octagonal-hendecagonal duoprisms, 8 square-hendecagonal duoprisms and 11 square-octagonal duoprisms. Each vertex joins 2 square-octagonal duoprisms, 2 square-hendecagonal duoprisms, and 1 octagonal-hendecagonal duoprism. Being a prism based on an orbiform polytope, it is also a convex segmentoteron.

Vertex coordinates
The vertices of an octagonal-hendecagonal duoprismatic prism of edge length 2sin(π/11) are given by all permutations of the first two coordinates of: where j = 2, 4, 6, 8, 10.
 * $$\left(±\sin\frac\pi{11},\,±(1+\sqrt2)\sin\frac\pi{11},\,1,\,0,\,±\sin\frac\pi{11}\right),$$
 * $$\left(±\sin\frac\pi{11},\,±(1+\sqrt2)\sin\frac\pi{11},\,\cos\left(\frac{j\pi}{11}\right),\,±\sin\left(\frac{j\pi}{11}\right),\,±\sin\frac\pi{11}\right),$$
