All exponents below 103313627 have been checked at least once.
This number is over 25% more than the exponent of the latest Mersenne prime discovered (82589933).

(The quoted post is presumed a joke, which a noob or two may not get.) Too late.Two ways. 1) I had run every known Mersenne prime from exponent 216091 up to through Mp48* in Gpuowl V7.035 back in October 2020 as software QA. Code:
{"status":"P", "exponent":"57885161", "worktype":"PRP3", "res64":"0000000000000001", "residuetype":"1", "errors":{"gerbicz":"0"}, "fftlength":"3145728", "proof":{"version":"1", "power":"8", "hashsize":"64", "md5":"2fba...760"}, "program":{"name":"gpuowl", "version":"v7.035gf06bc5b"}, "user":"kriesel", "computer":"asr2/radeonvii1", "timestamp":"20201020 14:57:03 UTC"} 2) All known GIMPSdiscovered Mersenne primes have already been at least LL DC and TC, and many QuadCheck or deeper during the verification of a new discovery.

Recent change to the Milestones page
We are making good progress. As we are getting closer to the milestone of double checking to M(57885161), which is (presumably) the 48th Mersenne prime, the Milestones page saw a very positive change today at about 16:00 UTC (noon Eastern Time). The countdown to M(57885161) now appears between the countdowns for 57000000 and 58000000. Here are the results as of the 16:15 UTC update of that page.
Countdown to verifying all tests below 56 million: 2 Countdown to verifying all tests below 57 million: 339 Countdown to verifying all tests below M(57 885 161): 2 563 (1 046 available) Countdown to verifying all tests below 58 million: 3 152 (1 408 available) P.S. Here is an archived version from three days ago as a reference; compare the current layout of the page with the layout in the linked capture of the page. https://web.archive.org/web/20210620...rt_milestones/ Last fiddled with by Raydex on 20210623 at 16:25

of the ~1500 assigned, I have 9 and they should all complete in 10 days or less. I am sure that I will pick up quite a few more before the milestone is reached. I have another machine that is still proving itself. It's 2 workers should start getting Cat 1's in about 4 or 5 days.

There's a thread for that.
The countdown to M(57885161) and to other known Mersenne primes have been appearing in the milestones page output for a long time. Last fiddled with by kriesel on 20210623 at 19:47

As kriesel pointed out, countdowns to Mersenne primes have been on the page for a long time; the Wayback Machine shows that it has been done at least as far back as 2008. https://web.archive.org/web/20081218...rt_milestones/ The most recent "doublecheck milestone" to a Mersenne prime to be completed was on April 8, 2018, when verifications surpassed M(43112609), the 47th Mersenne prime. For most of the 3 years, 2 months, 15 days since then, the countdowns to verifying all exponents up to those of known Mersenne primes have appeared together in the bottom subsection of the "Progress toward next GIMPS milestones" section. To clarify what I mean by that subsection, here is what the page looked like three days ago, according to the Wayback link a couple of posts ago. Countdown to verifying all tests below M(57 885 161): 3 154 Countdown to verifying all tests below M(74 207 281): 294 425 Countdown to verifying all tests below M(77 232 917): 349 899 Countdown to verifying all tests below M(82 589 933): 448 608 Now, this section contains only the last three bulleted countdowns, and the countdown for M(57885161) now appears in the section above it, right below the countdown to 57 million and right above the countdown to 58 million. The fourth bullet, of course, wasn't added until December 21, 2018, after M(82589933) was discovered and officially published (because Mersenne primes are kept secret for a week or two after their discoveries, before being publicly identified in a press release). From December 21, 2018 until about five hours ago, the structure of the last section remained the same, with only the countdown totals after the colons changing over time.
