(In reply to re: Start
From Google I learn that Fermat studied the curves x^3+y^3=Az^3 an stablish that if there is a non trivial solution then exists infinitely many.
Prestet working on Fermat get some formulas to obtain other solutions from one:
X=x(2y^3+x^3), Y=-y(2x^3+y^3), Z=z(x^3-y^3)
Using our solution (137, -65, 42) we get:
(277028111, 316425265, 119531076), all positive integers.
I'm not sure this is the smallest value, but Charlie's search makes it quite possible.
