Talk:Cantor-Bernstein-Schröder Theorem/Proof 6

Annoyance
The vast majority of this proof is spent on the simplest part, after the Knaster-Tarski lemma has been applied. Can anyone find some way to shorten this without handwaving? --Dfeuer (talk) 19:10, 1 April 2013 (UTC)

A Formal Version of this Proof
Here is my formal version of this proof. It is very long (1,262 lines), but each step is justified by one of a limited list of axioms and rules of inference I have developed based on simplified, more intuitive versions of FOL and ZFC.
