Abstract:
A set of at least two structural elements which may be intercleaved with each other for forming an assembly, said set comprising:a first structural element having at least two diagonally adjacent first physical polyhedral members and at least two first spatial polyhedral members sharing coincident first edge lines for forming a first edge set; a second structural element having at least two diagonally adjacent second physical polyhedral members and at least two second spatial polyhedral members sharing coincident second edge lines for forming a second edge set; wherein said first physical polyhedral members are the same polyhedral shape as said second spatial polyhedral members and said second physical polyhedral members are the same shape as said first spatial polyhedral members, but said first physical polyhedral members are of a different polyhedral shape from said second physical polyhedral members; and wherein at least one of said first edge set and said second edge set includes a cleft whereby said first structural element may be intercleaved to said second structural element by inserting said first physical polyhedral members into the voids formed by said second spatial polyhedral members.
