Found in a rational-parameter search of the Kubert–Tate family for torsion ℤ/2ℤ × ℤ/6ℤ: y^2 + (1-c)xy - by = x^3 - bx^2 with c=(10-2t)/(t^2-9), b=c+c^2, at t = 19/30; converted to the global minimal model. The 3 witness points were found with PARI/GP ellrank. Conductor 83973799470, torsion ℤ/2ℤ × ℤ/6ℤ.
