Patent ID: 6921314

Claim:
Generally polyhedral construction elements comprising a polyhedral body, within which a plurality of diagonally adjacent facet-based pyramidal recesses are formed, further forming a plurality of diagonally adjacent facet-based pyramidal members, and a plurality of difurcated edge sets, where said difurcated edge sets each comprise a plurality of coincident edges of diagonally adjacent facet-based pyramidal members, a plurality of coincident edges of diagonally adjacent facet-based pyramidal recesses interspersed among said diagonally adjacent pyramidal members, and a cleft implemented along an outermost portion of said coincident edges of said diagonally adjacent members, separating a corresponding portion of at least one of said members from the remaining diagonally adjacent member(s), and where each of said difurcated edge sets enables the interfitting of a first said construction element along said edge set with at least a second said construction element having a substantially complementarily formed and difurcated edge set; whereby the body of said first construction element penetrates into the body of said second construction element and the body of said second construction element simultaneously penetrates into the body of said first construction element in a mutually intercleaving, mutually interpenetrating manner.
