Theorem infxpenc 9632
Description: A canonical version of infxpen 9628, by a completely different approach (although it uses infxpen 9628 via xpomen 9629). Using Cantor's normal form, we can show that 𝐴o 𝐵 respects equinumerosity (oef1o 9313), so that all the steps of (ω↑𝑊) · (ω↑𝑊) ≈ ω↑(2𝑊) ≈ (ω↑2)↑𝑊 ≈ ω↑𝑊 can be verified using bijections to do the ordinal commutations. (The assumption on 𝑁 can be satisfied using cnfcom3c 9321.) (Contributed by Mario Carneiro, 30-May-2015.) (Revised by AV, 7-Jul-2019.)
