Oh, wow. This really is performing. I am up to 227424 as I start this week's processing. I am a bit into the 230's and the 240's as well. I wonder whether I will be able to find enough in this range to make 198 into 200!!

199? 472040

So, who's next?

robert44444uk · 2013-07-29, 10:50

Another amazing find.

I do not foresee any issues, but, in fact, I only ever look for prps as I have never had a prp issue with Payam numbers. So I am running all of the prps found to date through the n+1 test.

I can confirm the first 157 prps are in fact prime. I will post later to confirm the status of the range 158-199.

I've never posted a banana before, but.......

189 227776
190? 255530
191? 294807
192? 318934
193? 334623
194? 334645
195? 363020
196? 376732
197? 403709
198? 414907
199? 449150
200? 472040

We are not complete to 250000 yet. I have completed up to 227830, then 230001-233976 and 240001-242088. Other ranges up to 500000 to received reports from Thomas11 are 390001-400000, 458001-465000 before we can be sure of which prime is number 200, but there are 200 found.

Primes rather than prp are confirmed up to p=188

Thomas11 · 2013-07-29, 14:09

Congratulations, Robert!
That's indeed a good reason for a banana!

Well, I thought I would report the 200th prime, but just came a few minutes to late.
So it's already the 201st:

201? 479697
