rhombic dodecahedrons

Noun

rhombic dodecahedron (plural rhombic dodecahedra or rhombic dodecahedrons)

1. A convex polyhedron that has 12 congruent rhombic faces, 24 edges and 14 vertices of two types (eight 3-edge and six 4-edge) and is a Catalan solid.
   • Doing this we would find that the network which is dual to the space filling array of rhombic dodecahedra is the space filling array of tetrahedra and octahedra in which 12 edges meet at the vertices which fall at the centers of the original rhombic dodecahedra.1990, [1978], Peter Pearce, Structure in Nature Is a Strategy for Design, page 5
