Obtained by a rational 2-isogeny from curve #4899, submitted by Ritik Jain: https://elliptic-rank.icarm.cloud/curve/4899.
The source model is y^2 + x*y + y = x^3 - x^2 - 13629998356645502*x + 611263221986306397530125. Its public entry supplies eleven rational points and no commentary identifying an earlier source.
Applied the degree-2 isogeny with kernel generated by the rational order-2 point (64936249, -32468125), then converted the target to its minimal model y^2 + x*y + y = x^3 - x^2 - 8730752599246142*x + 1056657318427308749851405.
Eleven 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 2279229518497181053800334368402. Source-attributed existing curve.
