Under the assumption of the axiom of choice, this transfinite sequence includes every cardinal number.
en.wikipedia.org From 5th to 99th, ordinals are formed simply by declining the corresponding cardinal number as a regular adjective.
en.wikipedia.org The most common practice is to distinguish "een" (indefinite article, which, as a clitic, bears no stress) from "n" (the cardinal number one).
en.wikipedia.org Note that such a cardinal number exists, because the entire topology forms a base, and because the class of cardinal numbers is well-ordered.
en.wikipedia.org Formal-ontological categories relate objects and include notions such as set, cardinal number, ordinal number, part and whole, relation, and so on.
