Pentagonal-great rhombicosidodecahedral duoprism

The pentagonal-great rhombicosidodecahedral duoprism or pegrid is a convex uniform duoprism that consists of 5 great rhombicosidodecahedral prisms, 12 pentagonal-decagonal duoprisms, 20 pentagonal-hexagonal duoprisms and 30 square-pentagonal duoprisms. Each vertex joins 2 great rhombicosidodecahedral prisms, 1 square-pentagonal duoprism, 1 pentagonal-hexagonal duoprism, and 1 pentagonal-decagonal duoprism.
