I am using "fit" differently. X fits Y ⟺ X [≤] Y ⟺ exists 1.to.1 f: X ⇉ Y Yes ω < ω+1 < ω+2 < ... < ω+ω However, ω [≤≥] ω+1 [≤≥] ω+2 [≤≥] ... [≤≥] ω+ω ω [=] ω+1 [=] ω+2 [=] ... [=] ω+ω The distinction I make for WM is κ [≤≱] κ+1 [≤≱] ... ω [≤≥] ω+1 [≤≥] ... κ [<] κ+1 [<] ... ω [=] ω+1 [=] ... I'm sorry for the confusion. I am trying to shorten my posts enough that WM will read them. I am an eternal optimist. The stylistic choice I make is a two.edged sword. I feel it is a dynamic, very.readable style, leaning toward the Ernest.Hemingway.ish. However, deleting context courts confusion, as you have noticed.
