Theorem ordtypelem10 9499

Description: Lemma for ordtype 9504. Using ax-rep 5243, exclude the possibility that 𝑂 is a proper class and does not enumerate all of 𝐴. (Contributed by Mario Carneiro, 25-Jun-2015.)

Proof of Theorem ordtypelem10

Dummy variables 𝑏 𝑐 𝑚 are mutually distinct and distinct from all other variables.
