👉 In mathematics, the term "overdiverseness" is used to describe a situation where two or more sets have different cardinal numbers. This means that they do not share any elements in common, but instead contain different sizes of sets. For example, consider two sets A and B with cardinalities (or sizes) 100 and 200 respectively. These sets are considered overdiverseness if there exists a function f from the set A to the set B such that for
