The cardinality of a set A is defined as its equivalence class under equinumerosity. 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 … See more If the axiom of choice holds, the law of trichotomy holds for cardinality.
