%N A050794 Consider the Diophantine equation x^3+y^3=z^3+1 (1<x<y<z) or 'Fermat 
               near misses'. Arrange solutions by increasing values of z (see A050791). 
               Sequence gives values of x^3+y^3=z^3+1. For corresponding values 
               of x, y, z see A050792, A050793, A050791 respectively.
%C A050794 Note that a(1)=1729 is the Hardy-Ramanujan number. [From Omar E. Pol
