WebThe order of a set refers to the size of a set. It is also referred to as the cardinality of the set. Sets can have a finite or infinite order. If a set has a finite order, the order of a set is determined by the number of elements in the set. For example, the set A = {1, 2, 5, 7, 9} has an order of 5, since it contains 5 elements.

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.
