In http://hjem.get2net.dk/jka/math/cpap7402.htm Jens Andersen notes that ... That claim no longer holds; here is a larger CPrPAP-3: Primality testing...
... Congratulations! My note lasted a lot shorter than I had expected. It has been updated. The largest known CPAP's is only for proven primes but I just added...
"The wave" 2004 While googling for "The wave" 2004 I found: Ergebnisse 21 - 30 von ungefähr 2.620.000 für "The wave" 2004. (0,19 Sekunden) and the site ...
David, you are right. 192335307*2^25000-5131 is Fermat and Lucas PRP! 192335307*2^25000-1 is prime! 192335307*2^25000+5129 is Fermat and Lucas PRP! look like a...
The previous CPrPAP-3 record lasted for less than a day. Here is the new one: Primality testing 197418203*2^25000-6091 [N-1/N+1, Brillhart-Lehmer-Selfridge] ...
... Congrats again. I bet you wish the first had taken the 3%. I will update the link at my site when you stop finding daily records :-) -- Jens Kruse Andersen...
The first 101 titanic primes are 10^999+n for the following n: 7, 663, 2121, 2593, 3561, 4717, 5863, 9459, 11239, 14397, 17289, 18919, 19411, 21667, 25561,...
... Answer: 101, else the formula cannot be reliably parsed. Note: having proven all 101, only 31 are needed for KP. Nice one, Jens. Please email me a sieved...
Hi, ... I have the password for this Bio. I will update it with any blurb written by others relavent to e-group projects. Current projects: Jens' 100 titanic...
... Yes, it was a trick question. I was careful to certify and validate all 101 before sieving and prp'ing, although a pseudoprime like this would be a far...
... A note to participants. I would strongly NOT recommend using a -tc for a form such as this. There is no reason at all to use -tc for this, and it will...
Hi Jens, I'll take 500 also if that's OK Cheers Ken ... 18919, ... 41037, 41409, ... 61971, 62919, ... 78463, 79923, ... 102133, ... 129303, ... 145689, ... ...
... Jim, shouldn't that be -tp with a helper file? -tp N+1 test. uses the N+1 test to check whether the number is prime. This is NOT a probable test. You will...
... all ... You are correct. The -tp is what "should" be used. However, the -tp is much slower than the -t (-tm). If the original search would have used...

Dear Vladimir Mihailovich When your prime is too long for the CC parser, first give its digits as a "blob" at ...
Vladimir: I see that your "blob" is in process: http://primes.utm.edu/primes/page.php?id=73078 If you submitted it correctly, than it should end up like this...
Hi, all! ... It is a misprint. We can use -h since all factors are known to be prime. The safe command must be pfgw.exe -tc -n -Hpfgw-prime.log -lPrChF.log...
