No, the group theory one. I'd only before seen the inductive proof in Hirstein. There are really too many Cauchy's Theorems. I suppose the question is, why are they all known simply by that name and not more specific ones? I don't know how a "simple combinatorial proof" of that Cauchy's Theorem would be possible.
