The Dual Polyhedron of the Cuboctahedron, also sometimes called the Rhomboidal Dodecahedron (Cotton 1990). Its 14 vertices are joined by 12 Rhombuses, and one possible way to construct it is known as the Bauspiel. The rhombic dodecahedron is a Zonohedron and a SpaceFilling Polyhedron. The vertices are given by (, , ), (, 0, 0), (0, , 0), (0, 0, ).
The edges of the CubeOctahedron Compound intersecting in the points plotted above are the diagonals of Rhombuses, and the 12 Rhombuses form a rhombic dodecahedron (Ball and Coxeter 1987).
