%N A083378 a(n) = the largest integer whose cube has n digits and first digit 1; 
               but a(2)=2.
%C A083378 a(2)=2 because there is no integer with cube between 10 and 19.
%C A083378 A generalization to arbitrary powers is found in Huerlimann, 2003.
%C A083378 Non-mathematical comment: the line with the Huerlimann reference causes 
               the mail program "mail-dark" to think the line contains a virus.
