Found a couple small "EQ" (Eisenstein-Mersenne cofactors, OEIS [URL="http://oeis.org/A125743"]A125743[/URL]/[URL="http://oeis.org/A125744"]4[/URL]) (probable) primes:
(3^152809+3^76405+1)/7 is a 2-PRP!
(3^272141-3^136071+1)/7 is a 2-PRP!
(3^505823+3^252912+1)/7 is a 2-PRP! (241339 digits)
(3^1353449-3^676725+1)/7 is a 2-PRP! (645759 decimal digits) [B]Time: 10953.669 sec.[/B]

Notes:
1. The running time. With most tools you will get > 20000 sec. This is because of the implementation of FFT modulo 3[SUP]3p[/SUP]+1 with only final step done modulo N.
2. All of similar (composite or prime) numbers are 3-PRPs. Re-validating now with -b5, -b11.

Small prime, but for me it is huge :)

94 followed but 466002 number nine :)

The Riesel Problem: one less to go
 

A new elimination from the Riesel Problem is currently in the [URL="http://primes.utm.edu/primes/page.php?id=118583"]UTM queue[/URL] (into position 20!)

Congrats to PrimeGrid!

Another one!
502573*2^7181987 - 1 is prime!:smile:
Congrats to PrimeGrid.

Congratulations to my teammate!

99*10^303255-1 is prime! (303257 decimal digits, P = 33) Time : 2119.757 sec. :smile:

Hi Pepi

Congrats, but it seems it's not enough for top 20 near-repdigits:

I know that fact, but it is rare prime :)
Hunting is continued :)

Last was not in Top 5000 , but this fellow is :)

92*10^544905-1 is prime! (544907 decimal digits, P = 5) Time : 7082.969 sec.

Reported and verified on Top 5000 :)

Congrats. That is a lot of nines in its decimal expansion :smile:
