Square-small rhombicosidodecahedral duoprism

The square-small rhombicosidodecahedral duoprism or trasrid is a convex uniform duoprism that consists of 4 small rhombicosidodecahedral prisms, 12 square-pentagonal duoprisms, 30 teseracts and 20 triangular-square duoprisms.

Vertex coordinates
The vertices of a square-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 permutations and all sign changes of the last three coordinates of:
