Hexagonal-hendecagonal duoprismatic prism

The hexagonal-hendecagonal duoprismatic prism or hahenip, also known as the hexagonal-hendecagonal prismatic duoprism, is a convex uniform duoprism that consists of 2 hexagonal-hendecagonal duoprisms, 6 square-hendecagonal duoprisms, and 11 square-hexagonal duoprisms. Each vertex joins 2 square-hexagonal duoprisms, 2 square-hendecagonal duoprisms, and 1 hexagonal-hendecagonal duoprism. Being a prism based on an orbiform polytope, it is also a convex segmentoteron.

Vertex coordinates
The vertices of a hexagonal-hendecagonal duoprismatic prism of edge length 2sin(π/11) are given by: where j = 2, 4, 6, 8, 10.
