In mathematics, the cardinality of a set is a measure of the "number of elements of the set". For example, the set A = {2, 4, 6} contains 3 elements, and therefore A has a cardinality of 3. There are two approaches to cardinality - one which compares sets directly using bijections and injections, and another which uses cardinal numbers.

In Mathematics, the cardinality of a set is the number of elements it contains. So the cardinality of {3, 7, 11, 15, 99} is 5. The cardinality of {2, 4, 6, 8, 10, 12} is 6. * * * * * That is all very well for finite sets. But many common sets are infinite: integers, rationals, reals. The cardinality of all of these sets is infinity, but they are of two "levels" of infinity. Integers and rationals, for example have a cardinality of Aleph-null whereas irrationals and reals have a cardinality of aleph-one. It has been shown that there are no sets of cardinality between Aleph-null and Aleph-one.
