I don't think my writeup of Zolotarev's proof is the best -- the details would be much more transparent with a picture or two. The proof I wrote was part of a larger experiment -- if you click on the Theorem tab, you can see other theorems/axioms, etc.. that QR logically relies on. You can then trace those back further and further, and get all the way to the axioms of set theory! There's (more than) a few gaps, but hey.. it's an experiment. | |
