## Antichain Principle

Note: There is (as of 30.Sep.2015) no separate Wikipedia article on the Antichain Principle. However, in the Wikipedia article on the Axiom of Choice, the Antichain Principle is cited, under Order theory, as follows: "Every partially ordered set has a maximal antichain."

There is a Wikipedia article on antichains, which should, but does not (as of 30.Sep.2015) mention the Antichain Principle and its inferential equivalence to the Axiom of Choice.
