Great rhombidodecahedron

The great rhombidodecahedron, or gird, is a uniform polyhedron. It consists of 30 squares and 12 decagrams. Two squares and two decagrams meet at each vertex.

It is a faceting of the great dodecicosidodecahedron, using its 12 decagrams along with the 30 squares of the quasirhombicosidodecahedron.

Vertex coordinates
Its vertices are the same as those of its regiment colonel, the great dodecicosidodecahedron.
