Thanks :smile:
I am testing both k=2 and k=4 using PRP v.24.14 currently @ n=315000.

[URL="http://primes.utm.edu/primes/page.php?id=84401"]Another megaprime this year[/URL].

Yes, it's

24518^262144+1 (1150678 digits)

The new largest Generalized Fermat prime, found by Stephen Scott.
Currently ranked 13th.

Congrats!

[URL="http://primes.utm.edu/primes/page.php?id=84603"]Looks like we won't defend our current position in terms of score[/URL] :shock:

It's huge, congrats to them!

But it's reported jointly by two projects and they will share
credit, so we won't be far behind.

BTW, I also wonder what kind of "project" PrimeGrid is? They have reported so far twin candidates, Woodalls, and now Prime Sierpinski. They are also working on 3*2^n-1, and I heard they would like to run Proth and some generalized Woodalls. Looks to me like a team, not any particular project...

They have lots of different "subprojects", many of which are actually just BOINC faces on existing mersenneforum prime-search projects. Each user can choose in his preferences what mix of subprojects he'd like to be assigned work from. :smile:

I meant "project" on Top-5000 rankings. Each project there is supposed to be about a particular subset of all prime types, not primes of all types.
