Well, it's not confirmed yet...
I've run k=127 for many years; ten or so, I would guess. Since ~1M, I don't quite recall. The machine that made the discovery is a friend's office computer; it was found last August, but I only check the machine once a year or so. Whoops! Edit: I went and found the post: April 2007, from 1M up. http://mersenneforum.org/showpost.ph...&postcount=565 Last fiddled with by VBCurtis on 2018-06-25 at 22:42 |
