Specialization T=18371/22532 of the rank-nine X552 fibration posted by wgxli with curve#4061: y^2+238(19T-6)(5T-3)xy=x(x+F)(x+G), F=(12T-29)(51T+22)(79T+22)(482T+29), G=256(T-22)(83T-7)(21T-2)(7T+17). The nineteen supplied points have been checked exactly on the minimal model and certified independent modulo torsion by an exact rank-19 F_5 reduction matrix at nineteen good primes.
