Directed set bound of two elements is the desired "c". The converse does not hold however, witness the directed set {1000,0001,1101,1011,1111} ordered bitwise (e.g. 1000 ≤ 1011 holds, but 0001 ≤ 1000 does not, since in the last bit 1 > 0), where {1000,0001} has three upper bounds but no "least" upper bound, cf. picture. (Also note that without 1111, the set is not directed.) The order relation in a directed set is not required to be antisymmetric, and therefore directed sets are not always partial orders. However, the term "directed set" is also used frequently in the context of posets. In
