Well I think that solved my problem. If you add that as an answer, I'd be happy to upvote. Dec14 revised Prove that the statement implies the Axiom of Choice added 327 characters in body Dec14 asked Prove that the statement implies the Axiom of Choice Sep26 comment What does the notation $|f(A)| = X$ mean?
