Theorem oismo 9229
Description: When 𝐴 is a subclass of On, 𝐹 is a strictly monotone ordinal functions, and it is also complete (it is an isomorphism onto all of 𝐴). The proof avoids ax-rep 5205 (the second statement is trivial under ax-rep 5205). (Contributed by Mario Carneiro, 26-Jun-2015.)
Hypothesis
