%N A094376 Least number having exactly n representations as ab+ac+bc with 0 < a 
               < b < c.
%C A094376 Note that the Mathematica program computes A094376, A094377 and A094378, 
               but outputs only this sequence.

%e A094376 a(2) = 23 because 23 is the least number with 2 representations: (a,b,
               c) = (1,2,7) and (1,3,5).
