%N A092753 a(n) = smallest m >= 1 such that Sum_{k=1..m} log(k)/k >= n.
%C A092753 Sum (-1)^k log(k) / k is a conditionally convergent sequence that converges 
               to gamma log(2) - (log 2)^2 / 2. But the sum of the absolute values 
               diverges.
%e A092753 The sum of the first 4 terms is 1.059351276782648539882313867..., just 
               >= 1, so a(1) = 4.
