Theorem infxpencOLD 8421
 Description: A canonical version of infxpen 8413, by a completely different approach (although it uses infxpen 8413 via xpomen 8414). Using Cantor's normal form, we can show that respects equinumerosity (oef1oOLD 8163), so that all the steps of ( ) ( ) (2 ) ( 2) can be verified using bijections to do the ordinal commutations. (The assumption on can be satisfied using cnfcom3cOLD 8179.) (Contributed by Mario Carneiro, 30-May-2015.) Obsolete version of infxpenc 8416 as of 7-Jul-2019. (New usage is discouraged.) (Proof modification is discouraged.)
