Definitions
cofinality
Noun
In set theory, cofinality is the least ordinal number of a subset of a partially ordered set such that every element in the set is less than or equal to some element in the subset.
The cofinality of the set of natural numbers is omega, as it is the smallest ordinal with no upper bound in the set.
