Theorem infxpenc 8841

Description: A canonical version of infxpen 8837, by a completely different approach (although it uses infxpen 8837 via xpomen 8838). Using Cantor's normal form, we can show that 𝐴 ↑_𝑜 𝐵 respects equinumerosity (oef1o 8595), 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 8603.) (Contributed by Mario Carneiro, 30-May-2015.) (Revised by AV, 7-Jul-2019.)
