rhombic dodecahedron

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
   • Crystallographers are familiar with the rhombic dodecahedron as a domain of reference with which to account for the growth and structure of natural crystals.2007, Scott Eastham, American Dreamer: Bucky Fuller and the Sacred Geometry of Nature, page 160
