Based on the first 10^6 terms of A307730 we get 110 points on the upper envelope, which appear to lie very roughly on the curve y = x^0.57. It would be nice to have a more trustworthy expression for this curve! %H A348448 Rémy Sigrist, <a href="/A348448/b348448.txt">Table of n, a(n) for n = 1..10000</a> (first 110 terms from N. J. A.
