Dear Mathematica Gurus, Who know that existed any Mathematica procedure (library) to finding integral points on elliptic curves? Or how to find example to e.g. FindInstance[y^3 - x^2 == 1641843, {x, y}, Integers] if FindInstance doesn't work what inspite??? Unfortunatelly Wolfram Research is developing some branches of Mathematics in new versions of Mathematica and complete leave anothers (good samples are elliptic curves, Chabauty method, determining Galois groups of polynomials etc.). Best wishes Artur Jasinski
