Square-great rhombicosidodecahedral duoprism

The square-great rhombicosidodecahedral duoprism or squagrid is a convex uniform duoprism that consists of 4 great rhombicosidodecahedral prisms, 12 square-decagonal duoprisms, 20 square-hexagonal duoprisms and 30 tesseracts. Each vertex joins 2 great rhombicosidodecahedral prisms, 1 tesseract, 1 square-hexagonal duoprism, and 1 square-decagonal duoprism. It is a duoprism based on a square and a great rhombicosidodecahedron, which makes it a convex segmentoteron.

This polyteron can be alternated into a digonal-snub dodecahedral duoantiprism, although it cannot be made uniform.

Vertex coordinates
The vertices of a square-great rhombicuboctahedral duoprism of edge length 1 are given by all permutations of the last three coordinates of: along with all even permutations of the last three coordinates of:
