Decagonal-icosidodecahedral duoprism

The decagonal-icosidodecahedral duoprism or did is a convex uniform duoprism that consists of 10 icosidodecahedral prisms, 12 pentagonal-decagonal duoprisms and 20 triangular-decagonal duoprisms. Each vertex joins 2 icosidodecahedral prisms, 2 triangular-decagonal duoprisms, and 2 pentagonal-decagonal duoprisms.

Vertex coordinates
The vertices of a decagonal-icosidodecahedral duoprism of edge length 1 are given by all permutations of the last three coordinates of: as well as all even permutations of the last three coordinates of:
