Other Primes
I thought it would be nice to have a thread discussing primes found by others, or by us but not related to RPS.
And the first one is 2^12037932^601897+1 (362378 digits) new [URL="http://primes.utm.edu/top20/page.php?id=41"]Gaussian Mersenne norm[/URL] record set by Cruelty. More details can be found [URL="http://www.mersenneforum.org/showthread.php?p=87695#post87621"]here[/URL] Congratulations! The form can be searched using the latest version of LLR (3.7.x). I tried once at 400k but it was a bit time consuming (on my laptop) and I gave up. 
Earlier this month I found 99*10^1396701, the new [URL="http://primes.utm.edu/top20/page.php?id=15"]Nearrepdigit[/URL] record. In fact, 10 of the top 20 for this form have been entered in the last
23 months. 
Badges marking the latest 9.8Mdigit Mersenne prime are available in [URL="http://www.mersenneforum.org/showthread.php?t=6421"]this thread[/URL]. Sign up there if you'd like to have one.

(2^1127239+2^563620+1)/5 is 3PRP!, which AFAIK is the largest GQ so far :smile:
The question I have now is, how to prove it is, or it is not a prime :question: BTW: I don't consider using PRIMO or other ECPP based software for this purpose as it would take more than my life to complete :rolleyes:

[URL="http://www.mersenneforum.org/showthread.php?t=6657"]GQ(1127239) is PRP![/URL] Please post further replies there. 
Check [URL="http://primes.utm.edu/primes/page.php?id=78939"]this[/URL] out :shock:

Yes, huge
26773*2^24653431, 742147 digits. 20th of all times! Note that now an entry to Top100 requires binary exponent n>1.2M ! 
Monster
Someone, outside of this group I think has posted a monster
[url]http://primes.utm.edu/primes/page.php?id=79192[/url] 21st largest prime every found!!! 
That's L191, S. Banka who is (unfortunately :smile: ) not with us. He found 5 large primes in only one year, he began with 12121 project but now he is testing k=737 (=11*67) alone. He is now 13th by score!:surprised 4 of his 5 primes are currently in top100, only Cooper and Heuer have more primes in top100 while Grobstich has 4 too.

[QUOTE=Kosmaj;96369]... while Grobstich has 4 too.[/QUOTE]
... and Thomas has 4 in the Top101. :grin: 
Congrats to David Underbakke (L99) who just reported new largest SophieGermain pair (51910 digits):
48047305725*2^1724031 48047305725*2^1724041 Only 10 days after the new twin record!
