| May 29, 2014 at 15:55 | comment | added | Joe Silverman | Jeremy and I were answering a more general question, but you're right, the specific question is easier (although Nagell-Lutz is only marginally easier than the height argument). More generally, you're argument should work for $y^2=x^3+D$ with $D$ square-free. But it's not clear (to me) if it can be made to work for 6'th power free $D$. | |
