Jun 6, 2018 at 18:56 comment added fedja I think I can do it (both bounds). I'll try to post when I have time (unless somebody else figures it out faster)
Jun 6, 2018 at 5:17 comment added Scott Aaronson I also did a back-of-the-envelope calculation last night that led me to wonder whether $N^{1/3}$ was the right answer -- but I could prove it neither as an upper bound nor as a lower bound.
Jun 6, 2018 at 3:25 comment added fedja $N^{1/3}$ seems to be the right answer (up to a constant factor, of course), but that is just a back of envelope computation with no warranty attached to it.
Jun 5, 2018 at 20:22 comment added Scott Aaronson Yes, I was able to access some by proxy server. Others my university library did not have. In any case, I prefer to link to stuff that anyone reading my question can see. In that spirit, the following paper by Nisan and Szegedy has a nice self-contained proof of the "Ehlich-Zeller-Rivlin-Cheney theorem": hebuntu.cs.huji.ac.il/~noam/degree.ps It also, of course, has the bibliographic references.
