A representative set is designated for each equivalence class. The most common choice is the initial ordinal in that class. This is usually taken as the definition of cardinal number in axiomatic set theory. See more In mathematics, the cardinality of a set is a measure of the number of elements of the set. For example, the set $${\displaystyle A=\{2,4,6\}}$$ contains 3 elements, and therefore $${\displaystyle A}$$ has a cardinality of 3. … See more While the cardinality of a finite set is just the number of its elements, extending the notion to infinite sets usually starts with defining the notion of comparison of arbitrary sets … See more If the axiom of choice holds, the law of trichotomy holds for cardinality. Thus we can make the following definitions: • Any set X with cardinality less than that of the natural numbers, or X < N , is said to be a finite set. • Any set X that has the same cardinality as … See more • If X = {a, b, c} and Y = {apples, oranges, peaches}, where a, b, and c are distinct, then X = Y because { (a, apples), (b, oranges), (c, peaches)} is a bijection between the sets X and Y. The cardinality of each of X and Y is 3. • If X ≤ Y , then there exists Z such … See more A crude sense of cardinality, an awareness that groups of things or events compare with other groups by containing more, fewer, or the same number of instances, is observed in a variety of present-day animal species, suggesting an origin millions of … See more In the above section, "cardinality" of a set was defined functionally.
