Hendecagonal-great rhombicosidodecahedral duoprism

The hendecagonal-great rhombicosidodecahedral duoprism or hengrid is a convex uniform duoprism that consists of 11 great rhombicosidodecahedral prisms, 12 decagonal-hendecagonal duoprisms, 20 hexagonal-hendecagonal duoprisms and 30 square-hendecagonal duoprisms. Each vertex joins 2 great rhombicosidodecahedral prisms, 1 square-hendecagonal duoprism, 1 hexagonal-hendecagonal duoprism, and 1 decagonal-hendecagonal duoprism.

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