496. Today, that GNFS candidate M1087 has been factored by using some of the ECM curves only! I know about that number falling off below 500 before itself!

PERFECT NUMBER indeed! M935 really tomorrow? Quite Possibly.

That's two Bos-Kleinjung ecm factors, p63 and p61, so the average
expected smallest prime factor is p62? Limits dropped from B1= 3e9
to B1 = 260e6, p60-optimal (uhm, 3e9 = 30e8 = 300e7 = 3000e6, dropped
by a factor of 10, more or less). I'd done testing to p55 (6t50). -Bruce
