Grand hendecagrammic-dodecagrammic duoprism

The grand hendecagrammic-dodecagrammic duoprism, also known as the 11/5-12/5 duoprism, is a uniform duoprism that consists of 12 grand hendecagrammic prisms and 11 dodecagrammic prisms, with 2 of each at each vertex.

Coordinates
The vertex coordinates of a grand hendecagrammic-dodecagrammic duoprism, centered at the origin and with edge length 2sin(5π/11), are given by: where j = 2, 4, 6, 8, 10.
