The curves are given in the form [a1 a2 a3 a4 a6].
There are four classes of curves here, which I've colour-coded in what I hope is a meaningful way:
Green | Curve is known to have the smallest conductor for that rank, as a result of an exhaustive search over conductors |
Blue | Curve is known to have the smallest conductor for that rank among curves with max(a4,a6) <= its value of max(a4,a6) |
Pink | Curve was found by the sieve-driven search documented here (with bounds |a4|<=20000, |a6|<2^24) |
Grey | Curve was found by a Mestre-style method (mine is documented here): the rank has not always been proven not to be more than I claim |
If the conductor is displayed in a saturated (rather than a pastel) colour, it is prime.
