I've been keeping a tally on a spreadsheet and you are correct. 181 and 185 have had 3 primes each (in the Top-5000). There are still 9 k's for which we have found no primes yet.

to make up for the large gap between the previous primes. :geek:

[QUOTE=Kosmaj]Congrats to Curtis on new primes
3803443215*2^383049-1
3803443215*2^380349-1

but exponents are so similar, I'm afraid one was a typo (?)[/QUOTE]
Yep-- I felt pretty dumb about 1 second after hitting "confirm" on the 380349 submission. It was removed from the list later that day, as it wasn't prime.

On the bright side, I found another prime later that week:
3803443215*2^390317-1.
This makes 11 primes above 200k for this k-value, with a range of about 10,000 left to search below 400,000. Is this unusually good? I only have it sieved to 500k.. should I consider a new sieve for this richness?

834405*2^257151-1 (77417 digits)

Kosmaj 2006-04-24 01:46

Curtis,
No problems. Yes, 11 primes in the 200-400k range is a lot! More than any of 16 k's in our First Drive (processed to about 360k now). If you can sieve more go for it, and if/when you cannot test it by yourself we'll help you. :cool:

BTW, a new prime for k<300
177*2^277458-1 (83526 digits)

VBCurtis 2006-04-24 20:04

Make that 12 in the 200-400k range:
3803443215 396082 is prime.
I guess I'll be sieving to 1 million and continuing this k-value past 500k.
Sieving is slow- it has to be entered into NewPGen in factored form, so I only sieved the 0-500k range to 600B.
-Curtis

Kosmaj 2006-04-24 21:49

One more for k=177:
[B]177*2^282546-1[/B] (85058 digits)

Curtis, when k>2^31, it's faster to sieve k*2^n-1 using ksieve. If you cannot find a copy of ksieve let me know, I'll send you one.

And congrats to [B]NiceMedTexMD[/B] on many new primes!
