smallcardinality
Smallcardinality is a term used to describe the size of a set when the number of elements is considered small within a given context. In typical mathematical usage, this usually means the set is finite; by contrast, infinite sets have cardinalities that are not finite natural numbers. The concept centers on the notion of cardinality, denoted |X|, which assigns a size to a set X in a way that distinguishes different levels of infinity from finite sizes.
Formally, a set X is finite if there exists a natural number n such that |X| = n.
In applied settings, small cardinalities enable explicit enumeration and combinatorial counting, such as computing the number
