%C The limit supremum of F(n)/n^theta is 1. - _Charles R Greathouse IV_, Oct 30 2016

%C Named by Finch (2003) after Kenneth B. Stolarsky and Heiko Harborth. Stolarsky (1977) evaluated that its value is in the interval [0.72, 0.815], and Harborth (1977) calculated the value 0.812556. - _Amiram Eldar_, Dec 03 2020
