cofinality

Substantiv

/ˌkəʊfaɪˈnælɪti/

/ˌkoʊfaɪˈnælɪti/

In set theory, the least ordinal α such that a partially ordered set (or ordinal) has an unbounded (cofinal) subset of order type α; equivalently, the minimal cardinality of a cofinal subset.

The cofinality of the ordinal ω is ω, because the natural numbers themselves form an unbounded subset of order type ω.
