https://en.wikipedia.org/wiki/Well-orderIn mathematics, a well-order (or well-ordering or well-order relation) on a set S is a total order on S with the property that every non-empty subset of S has a least element in this ordering. The set S together with the well-order relation is then called a well-ordered set. In some academic articles and

https://en.wikipedia.org/wiki/Well-ordering_theoremIn mathematics, the well-ordering theorem, also known as Zermelo's theorem, states that every set can be well-ordered. A set X is well-ordered by a strict total order if every non-empty subset of X has a least element under the ordering. The well-ordering theorem together with Zorn's lemma are the most important mathematical statements that are equivalent to the axiom of choice (often called AC, see also Axiom of choice § Equivalents). Ernst Zermelointroduced the axiom of choic…

The Well-ordering Principle | Brilliant Math & Science Wiki
https://brilliant.org/wiki/the-well-ordering-principleThe well-ordering principle says that the positive integers are well-ordered. An ordered set is said to be well-ordered if each and every nonempty subset has a smallest or least element. So the well-ordering principle is the following statement: Every nonempty subset S S S of the positive integers has a least element.. Note that this property is not true for subsets of the integers (in …
