Description: In this paper we study the properties of a relation, H, between two sets, X and Y, H ⊆ X x Y. We wish to determine when the existence of H between some elements of X and Y implies the existence of H between other composite elements of X and Y. The aim is to characterize a relation by its extension or restriction to composite elements.
