That's fantastic Van, well done you and your little 1060 tool :). I'd love to do some GFN melée myself to move it off 85M park - there's a challenge in Nov which'll be a break from the AP slog.
Let's celebrate with Saturday evening cheese toasties. |

It's a big number. He might need to insert it between pages 12 and 826.

I certainly appreciate the warm response, though congratulations should really go to everyone. Someone had to crunch the workunit before that, and the tens of thousands before that, and someone had to sieve to thin out the possible candidates. That someone is really everyone here at PG.
A lot of work went in to finding it, and I just happened to be in the right place at the right time. |

Probably at least that.
My largest prime was discovered in 2012 with just under 400k digits and it entered the lists at about 400th. It still hangs on in the list.
My first reportable prime back in Oct 09 with nearly 150k digits entered the list at about 1950 and stayed on the list for nearly a year. |

A bit tardy in my congratulations, Mr. VZ, but well done!.
(I'd set my lonely little box on 321 for the challenge, and then was "out of the office" for a few days.)
Anyway it is up to the rest of us to better his record! :-)

Thanks! This one was extra-special for me because it is 1) my largest prime find, 2) my 100th GFN find, and 3) my only GFN18, which now gives me a set of GFN 15, 16, 17, and 18 finds.
Time to move over to GFN19 and see if we can't get lucky there, too! :)
