Rationally 2-isogenous to the rank-7 curve [0,1,0,-59183049,174279405895] in Michael Rubinstein’s elliptic-curves-by-rank repository, torsion_Z2.add_2026-10-24.part1.tsv.gz, source index 588815.
The source points were transported through the degree-2 isogeny to the minimal model [0,1,0,-5960639,-1003279199]. Using these points, PARI/GP returned matching rank bounds [7,7] and the seven independent points listed here. All seven were checked exactly on this model. Rational torsion Z/2Z.
