Obtained by a rational 2-isogeny from curve #4695, submitted by dujella: https://elliptic-rank.icarm.cloud/curve/4695. The source commentary credits Watkins (2002). The source model is y^2 = x^3 + 402599774387690701016910427272483*x. Applied the degree-2 isogeny X = (x^2 + A)/x, Y = y*(x^2 - A)/x^2 with A = 402599774387690701016910427272483. The resulting model is Y^2 = X^3 - 1610399097550762804067641709089932*X. Fourteen supplied rational points transported through this map and checked exactly on the target curve. Rational torsion Z/2Z. Same rank and conductor as the source; conductor 576307834087180278659283541515639524426406638619391775412369725472. Source-attributed existing curve.
