Pentagonal-hendecagonal duoprism

The pentagonal-hendecagonal duoprism or pahendip, also known as the 5-11 duoprism, is a uniform duoprism that consists of 5 hendecagonal prisms and 11 pentagonal prisms, with two of each joining at each vertex.

Vertex coordinates
The coordinates of a pentagonal-hendecagonal duoprism, centered at the origin and with edge length 2sin(π/11), are given by: where j = 2, 4, 6, 8, 10.
