Great rhombicosidodecahedral prism

The great rhombicosidodecahedral prism or griddip, is a prismatic uniform polychoron that consists of 2 great rhombicosidodecahedra, 12 decagonal prisms, 20 hexagonal prisms, and 30 cubes. Each vertex joins one of each type of cell. as the name suggests, it is a prism based on the great rhombicosidodecahedron. As such it is also a convex segmentochoron (designated K-4.150 on Richard Klitzing's list).

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

Vertex coordinates
The vertices of a great rhombicosidodecahedral prism of edge length 1 are given by all permutations of the first three coordinates of: along with all even permutations of the first three coordinates of:
 * (±1/2, ±1/2, ±(3+2$\sqrt{2}$)/2, ±1/2)
 * (±1/2, ±(2+$\sqrt{3}$)/2, ±(4+$\sqrt{(5+√5)/2}$)/4, ±1/2)
 * (±1, ±(3+$\sqrt{2}$)/4, ±(7+3$\sqrt{8+3√5}$)/4, ±1/2)
