649*2^476415-1 is prime! Time : 792.0 sec.
10 days late but better late than never. :smile:

939*2^497824-1 is prime

We're finally starting to roll again:

803*2^497908-1 is prime

The single greatest k for NPLB?...
 

Rollin', rollin', rollin' ... :smile:

871*2^498385-1 is prime


k=871 is likely the single greatest k for NPLB. This makes an incredible EIGHT top-5000 primes for this k reported by our project including two for yours truly! I haven't even checked drive 2 for non-reportable primes.

429*2^499671-1 is prime.

They come in 3's...
 

451*2^501525-1 is prime
519*2^501728-1 is prime
883*2^501779-1 is confirmed prime

David, my mouth dropped when I saw this on your web page so I had to double check the first two with success. Everything looks like it's working great on your web pages!

In the words of Chris (Flatlander), I now own 2% of the top-5000! lol

Nice catch on port 400 :)
