Found 2026-10-01 in a discriminant-first search for elliptic curves over Q with rational 2-torsion. The search used the visible-2-torsion family y^2 = x^3 + A*x^2 + B*x and a Kretschmer-type four-square pattern with B = 5*109*199 = 108455 and A = 1105. PARI/GP 2.17.4 on the global minimal model gives ellrank bounds [6,6], torsion Z/2Z, conductor 341505273100, and minimal discriminant 148151817576242000. The six submitted points are the independent generators returned by ellrank(E,1).
