Hendecagonal-small rhombicosidodecahedral duoprism

The hendecagonal-small rhombicosidodecahedral duoprism or hensrid is a convex uniform duoprism that consists of 11 small rhombicosidodecahedral prisms, 12 pentagonal-hendecagonal duoprisms, 30 square-hendecagonal duoprisms and 20 triangular-hendecagonal duoprisms. Each vertex joins 2 small rhombicosidodecahedral prisms, 1 triangular-hendecagonal duoprism, 2 square-hendecagonal duoprisms, and 1 pentagonal-hendecagonal duoprism.

Vertex coordinates
The vertices of a hendecagonal-small rhombicosidodecahedral duoprism of edge length 2sin(π/11) are given by all permutations of the last three coordinates of: as well as all even permutations of the last three coordinates of: where j = 2, 4, 6, 8, 10.
