(mathematics) Given a binary operation → β {\displaystyle \rightarrow _{\beta }} on a set A, and its reflexive, transitive closure ↠ β {\displaystyle \twoheadrightarrow _{\beta }} , then, for all a1, a2, and a3 in A, if a1 → β {\displaystyle \rightarrow _{\beta }} a2 and a1 → β {\displaystyle \rightarrow _{\beta }} a3, then there must exist an a4 in A such that a2 ↠ β {\displaystyle \twoheadrightarrow _{\beta }} a4 and a3 ↠ β {\displaystyle \twoheadrightarrow _{\beta }} a4.
