Hi to an old friend (henryzz)

[diep]

Wanting to say hi to D. Stevens - anyone have his e-mail address or is he frequently checking out over here?

I see a D. Stevens mentionned at 2 Riesels. Last update 2010 and 2008 for k=8413. Says checked out up until only 100k.

Wanna have a shot at a low weight formula besides the 69 * 2^n - 1 i'm doing which moves slow by now; might be lucky soon with 1 or 2 megaprimes yet after that next prime for 69 might take many years therefore interested in taking a lottery ticket with a low weight huge k.

Now it's possible that rieselprime.de isn't very much up to date for such bizarre huge k's for which reason i'm trying to locate D. Stevens wanting to ask him how active he's still hunting for primes with k=8413...

My first in a while and as a consequence my largest.

He's still active, I'd send him a PM if I were you.

Already done, thanks!

I think my data are more up to date for such 'big' k-values than smaller ones, because RPS and NPLB are searching in much lower k-ranges and therefore find more primes, which I try to update in the next time.
As you mentioned, there're 2 posts herein from henryzz with topic k=8413. I unreserved this k for him therefore, so he's not working on this one (others I don't know from).
Information about those higher k-values are rare and the only pages I can get some is here or Caldwells primelist (btw you can find 2 "Stevens" in his list and one D.Stevens with user 'henryzz').
Next time you can contact me also: I got a list of real names and logins (an old one can still be found on www.15k.org -> Contributors but this without henryzz).

Yes, thanks for the explanations, i got the same answer back from henryzz in a message that he must've unreserved it otherwise he would've searched it deeper.

Hereby i'm reserving 8413 * 2^n - 1 and will have a shot at it.

Thanks,
Vincent

Your reservation is online, faster won't go

k=8413 checked to 500k. No new primes. Unreserving. (posted for those who find this thread some years from now when googling for k=8413 and wonder about its status)
