I guess [url]http://www.mersenne.org/primes/[/url] needs to updated to remove the asterisk.

There's no better birthday present than a new GIMPS milestone, especially one that confirms a Mersenne prime's place in line! :smile:

Just four days shy of eight years (from one end of the Obama administration to the other!) between discovery and final confirmation. Seems like only yesterday that these twins were found.

Ah, whoops, yeah. I think George might have that fixed by now... he beat me to it. :smile:

Now I know why we found out M47* before M45. That was because the graphic on the bottom of that page to look nice. Otherwise, M46* and M47* dots would have been overposed on top of each other and we could not see them clearly. And you tell me there is no god... :davar55:

Can you please post a link to the graph?

You are absolutely right! :bounce:

Another little milestone!

All exponents below 68M have been tested at least once.

Smallest double-check : is it jinxed ?
 

Some exponents will just not finish, sometimes even when almost done. For instance the smallest exponent needing a double check : [url=http://www.mersenne.org/report_exponent/?exp_lo=37513111&full=1]M37513111[/url], it was less than 15 % from completion during the penultimate abandoned attempt and less than 7 % during the last.

I hope to have it finished tomorrow 2016-10-16 round 20:10 UCT.

A few misc. milestones that interest me....
 

Besides those regularly chatted about; i.e. 50th Prime.

We may or may not see any of these in 2017

1. When 80% of exponents < 1 Million are either Factored or Prime.
[url]http://www.mersenne.org/primenet/[/url]
-- Currently at (62,155+33)/78498 = 79.22%

2. When there are a total of 30 Million Factored exponents
[url]http://www.mersenne.ca/status/tf/0/0/1/0[/url] ... for next 2 as well
-- Currently at 28,984,181

3. When there are a total of less than 20 Million Un-Factored exponents
-- Currently at 21,863,304

4. When all exponents above 30 Million are factored to 70 bits.
