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.

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