The **chirorhombidodecahedron**, **rhombidodecahedron**, **kred**, or **compound of six pentagonal prisms** is a uniform polyhedron compound. It consists of 30 squares and 12 pentagons, with one pentagon and two squares joining at a vertex.

Its quotient prismatic equivalent is the pentagonal prismatic hexateroorthowedge, which is eight-dimensional.

## Vertex coordinates[edit | edit source]

The vertices of a chirorhombidodecahedron of edge length 1 are given by all permutations of:
