I'm happy the article is started, but at present it does not actually define anything. But defining the $\aleph$ notation probably requires using all kinds of proofs about injections between well-orders and all that mess. It's all been a bit long for my taste, and I can't devote time to this at the moment. Anyone else up for it? — Lord_Farin (talk) 12:31, 10 October 2018 (EDT)
