Apr 7, 2010 at 22:40 | comment | added | Kevin Buzzard | [remark: the biggest integer point on either curve is 5*532^3+4=27438^2, but, unfortunately, 532 isn't a square] | |
Apr 7, 2010 at 22:35 | comment | added | Kevin Buzzard | It's really easy to get a computer to find all the integer points on an elliptic curve, as I was just saying the other day at mathoverflow.net/questions/20286/… . Multiply up by 25 and we're looking for integer points to X^3+-100=Y^2 (with X,Y both multiples of 5). Both magma and sage have got this implemented now: you just type "IntegralPoints(EllipticCurve([0,100]));" into magma for one, and change 100 to -100 for the other. Both commands terminate in about 0.2 seconds. | |
