One could prove the Riemann hypothesis if one could show that some certain arithmetical sums are of a constant sign. Two such sums, studied by Polya and Turan, are known not to be of a constant sign. Mike Mossinghoff and I looked at generalisations of these sums; in this talk I will give details of the sum most likely to be of constant sign.
