Re: [math-fun] permuting via rational functions

This one in English apparently has something to do with it too:

Leonard Carlitz: A note on permutation functions over a finite field, Duke Math. J. 29 (1962) 325-332.

--It seems Carlitz invented pretty much the same idea RC Schroeppel had posted earlier about generating permutations via polynomials, as is revealed by reading this nice paper: Michael E. Zieve: On a theorem of Carlitz, J. Group Theory 17 (2014) 667-669 http://arxiv.org/abs/0810.2834 -- Warren D. Smith http://RangeVoting.org <-- add your endorsement (by clicking "endorse" as 1st step)
