There is an axiom/lemma from Teichmilles & Tukey that is equivalent to the axiom of choice. It reads,

Every family of sets F that is of finite character (http://en.wikipedia.org/wiki/Finite_character) possesses a maximal element.

I just want to confirm that here, "maximal set" means a set that is itself contained in no greater set?
