Octagrammic-great hendecagrammic duoprism

The octagrammic-great hendecagrammic duoprism, also known as the 8/3-11/4 duoprism, is a uniform duoprism that consists of 11 octagrammic prisms and 8 great hendecagrammic prisms, with 2 of each at each vertex.

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