Found by exhaustive Mestre-Nagao sieve (16-bit fixed-point C sieve, 2^8-stage cutoffs, ~10^8 specializations) over the Tate normal form universal family y^2+txy+(t+2)y=x^3 with torsion Z/6Z, at t=-2887/319. Rank 5 with full Mordell-Weil basis certified by mwrank (eclib) 2-descent; torsion verified exact order 6.
