Equinumerosity is a concept in mathematics, particularly in set theory, that refers to the property of two sets having the same cardinality, or the same "number of elements." Two sets \\( A \\) and \\( B \\) are said to be equinumerous if there exists a one-to-one correspondence (or bijection) between the elements of the sets.
