Found 2026-10-01 in a discriminant-first search for elliptic curves over Q with rational 2-torsion, using the family y^2 = x^3 + A*x^2 + B*x and screening low-discriminant candidates. PARI/GP 2.17.4 on the global minimal model gives ellrank bounds [4,4], torsion Z/2Z, conductor 909085056, and minimal discriminant 1818170112. The four submitted points are the independent generators returned by ellrank(E,1).
