Octagonal-great rhombicosidodecahedral duoprism

The octagonal-great rhombicosidodecahedral duoprism or ogrid is a convex uniform duoprism that consists of 8 great rhombicosidodecahedral prisms, 12 octagonal-decagonal duoprisms, 20 hexagonal-octagonal duoprisms and 30 square-octagonal duoprisms.

This polychoron can be alternated into a square-snub dodecahedral duoantiprism, although it cannot be made uniform. The octagons can also be alternated into long rectangles to create a bialternatosnub snub dodecahedral-square duoprism, which is also nonuniform.
