Thanks
I am testing both k=2 and k=4 using PRP v.24.14 currently @ n=315000. Last fiddled with by Cruelty on 20080310 at 08:44

Yes, it's
24518^262144+1 (1150678 digits) The new largest Generalized Fermat prime, found by Stephen Scott. Currently ranked 13th. Congrats!

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^n1, and I heard they would like to run Proth and some generalized Woodalls. Looks to me like a team, not any particular project...

I meant "project" on Top5000 rankings. Each project there is supposed to be about a particular subset of all prime types, not primes of all types.
