In mathematics, an ordered pair (a, b) is a pair of objects. The order in which the objects appear in the pair is significant: the ordered pair (a, b) is different from the ordered pair (b, a) unless a = b. (In contrast, the unordered pair {a, b} equals the unordered pair {b, a}.)

WebThe ordered pair ( a, a), as a set, is a set which can be written as { { a }, { a, a } } or as { { a }, { a } } or as { { a } }.
