Octagonal-small rhombicosidodecahedral duoprism

The octagonal-small rhombicosidodecahedral duoprism or hesrid is a convex uniform duoprism that consists of 8 small rhombicosidodecahedral prisms, 12 pentagonal-octagonal duoprisms, 30 square-octagonal duoprisms and 20 triangular-octagonal duoprisms.

Vertex coordinates
The vertices of an octagonal-small rhombicosidodecahedral duoprism of edge length 1 are given by all permutations and sign changes of the last three coordinates of: as well as all even permuations and all sign changes of the last three coordinates of:
