Also, on al elliptic curve over Q yo ucan use heights to avoid a generic discrete log computation. Here,
sage: Q.height()/P.height() 1.00000000000000 suggests that Q-P (or (Q+P) is torsion, and indeed, sage: P-Q (0 : 0 : 1) sage: (P-Q).order() 2 John Cremona On Saturday, May 26, 2012 10:14:07 PM UTC+1, raman wrote: > > Hi Dears, > I have the elliptic curve Y^2=X^3-36X and P=(-3,9) as the its > generator.
