Decagonal-great rhombicosidodecahedral duoprism

The decagonal-great rhombicosidodecahedral duoprism or dagrid is a convex uniform duoprism that consists of 10 great rhombicosidodecahedral prisms, 12 decagonal duoprisms, 20 hexagonal-decagonal duoprisms and 30 square-decagonal duoprisms.

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

Vertex coordinates
