%N A222761 Conjectured lower bounds for the Riemann hypothesis function floor(H(k) + exp(H(k))*log(H(k))) - sigma(k).
%C A222761 Here H(k) is the k-th harmonic number, Sum_{i=1..k} 1/i, and sigma(k) is the sum of the divisors of k. This sequence gives the conjectured values of A057641 that form a lower bound. For instance,
%C A222761 all numbers x <= 0 appear for n <= 12 = A176679(3);
%C A222761 all numbers x <= 1 appear for n <= 24 = A176679(4);
%C A222761 all numbers x <= 2 appear for n <= 60 = A176679(5);
%C A222761 all numbers x <= 6 appear for n <= 120 = A176679(6);
%C A222761 all numbers x <= 23 appear for n <= 180 = A176679(7).
%C A222761 The pattern continues.
