Obtained by a rational 2-isogeny from curve #52, submitted by David Renshaw: https://elliptic-rank.icarm.cloud/curve/52.
The source model is y^2 = x^3 - 2827529113871322622866959217*x. Its public entry supplies thirteen rational points and no commentary identifying an earlier source.
Applied the degree-2 isogeny X = (x^2 + A)/x, Y = y*(x^2 - A)/x^2 with A = -2827529113871322622866959217. The resulting model is Y^2 = X^3 + 11310116455485290491467836868*X.
Thirteen 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 28426385385919811326943632130923115672884025713568899872. Source-attributed existing curve.
