Hi hope everyone has been keeping ok?

I have been sticking to the PPSE work units I have completed over 1800 Work units on CPU, will I have to complete a lot more to find a prime. which i more than happy to do.

I have also found four AP20s here is my first find 200192410653469237+138288308*23#*n for n=0..19 have I discovered my first prime?

I have also been running Generalized Fermat GFN-15 on GPU, what is the diffrence between GFN-15 up to GFN World Record, is that the higher the number i.e GFN-16 and onwards the longer the prime number will be?

Can someone explain what the diffrence between GFN projects and PPSE is? please,


Thank you.

Lame answer (someone else will be able to provide a better one):
The higher the number next to GFN, the longer it will take to complete. From a few seconds on GFN 15 to several days (or even weeks) on GFN world record.
The latter name means that if a GFN WR candidate turns out to be prime, it would be the largest prime number ever found.

PPS and GFN have the same purpose: find prime Numbers. They use different software (although both run within Boinc). PPS is currently CPU online while GFN runs on CPU or GPU.

"GFN-WR" is a misnomer now for a few years since GIMPS found the new world's biggest, that's what DYFL is for. The front page shows you predicted world position for each project.

The GFN-WR Project is now called "Do you feel lucky". The largest prime found by GIMPS has 24862048 digits. If we were lucky enough to find a (GFN) prime running tasks from "Do you feel lucky", it would be the largest prime ever found.

Um... not exactly.

GFN-WR is now called GFN-22, although its internal, immutable name must remain genefer_wr.

DYFL (Do You Feel Lucky?) is an entirely new project. It fulfills the same purpose as GFN-WR used to fulfill, but it's a different project.

GFN-WR as a project name no longer exists.

I have also found four AP20s here is my first find 200192410653469237+138288308*23#*n for n=0..19 have I discovered my first prime

There was some discussion of that question here. It's a surprisingly philosophical question. Those 20 primes are small enough that some computer probably
noticed their primality before you, but probably no human did. And really, 18-digit primes are so easy to find (e.g. type some random numbers in here) that the only interesting thing about them is that they form an AP--which is exactly what you discovered.

In any case, congrats on the discoveries, and keep up the good work--I see you've already passed me in total credit.
