Looks like the 12121 search may have found a 1 million digit prime [url]http://primes.utm.edu/primes/page.php?id=86608[/url]

The verification failed :sad:
The question now is whether it was a typo, or a software or hardware error. Anyway, I wish them to find their first megadigit prime soon! 
Cullen record
Congrats to PrimeGrid on the new record Cullen prime:

a new Mersenne prime was verified : [url=http://primes.utm.edu/primes/page.php?id=88847]2^426438011[/url]!

[QUOTE=Harvey563;178753]45444*512^454431[/QUOTE]
so this is a new entry for [url]http://www.geocities.com/harvey563/NearCullen_WoodallPrimes.txt[/url] as 11361*2^4089891 with 123123 digits! why this prime wasn't found before although the high limit on the above link is given as n=543000!? so this range only counts for base=2, but not others. and the special base 512 > 2^9 makes this prime more harder to find. so the 'normal' sieve is for (n+1)*2^n1, but for a base with power x of 2 someone has to sieve: (n+1)*2^(n*x)1!? for example x=10 the sieve/test for n+1 Near Woodall is like: 1001*2^100001 1002*2^100101 1003*2^100201 and so on. correct? or i'm totally wrong here?

No it's not. The link lists "NearCullen & NearWoodall primes" (see the title) considering only base 2, while the reported prime is [U]Generalized[/U] near Woodal, to base 512.

It is also a top 15 prime at over 2M digits and the largest found by LLR. Additionally, it is PrimeGrid's largest prime to date. The discoverer is from Japan and a member of [URL="http://www.primegrid.com/team_display.php?teamid=194"]Team 2ch[/URL]. Verification is in progress. Stay tuned for more details. [/quote]
