Comment (by cremona):
Replying to [comment:10 jdemeyer]:
> Coefficient = one of a1,a2,a3,a4,a6
sage: E = EllipticCurve('50568m1'); E.ainvs()
(0, -1, 0, -37998022884432, 90154970279923910796)
sage: RR(E.a6().abs()).log(2.0)
66.2890408330703
but the conductor is rather large for the modular symbol computation to be
reasonable in a test.
