Bases 6-32 reservations/statuses/primes - Page 36

I've reached the end of my reservation for Riesel 19 at n = 30,000. I won't continue with the bulk, but I am taking k = 366 to 200,000. Currently it is at 140,000.

Here are the primes that I found for base 7. I've confirmed them with PFGW as well.
257318*7^63295-1
747176*7^60757-1
48584*7^56816-1
493032*7^51053-1
184434*7^46243-1
913284*7^45093-1

The search has progressed until k = 67,000

I forgot to say that I took all k < 10,000 to n = 100,000. That netted 6 primes and left 5 k in that range: 366 3224 3314 3926 8006

Riesel base 24is now at n=32,5
Sierpinski base 24 is now at n=33,9

Unfortunately I had too little time at the comp. to assess how many k's remain, but next time I'll update that too :)

It appears as though I won't get to 100k any time soon...

I have restarted Sierp base 12 k=404 and it is now at n=180K; no primes.

Continuing to n=200K, then will pause for a while to sieve further before continuing up to n=250K.

gd_barnes · 2008-09-03, 07:08

Sierp base 12 k=404 is at n=190K. Nothing to report. Continuing on...

Testing time jumped by ~30% from 3220 secs. to 4225 secs. at n=187.6K. (bleh!)

Whew, these higher bases take a long time just to get to n=200K for a single k!

n=100K is a HUGE undertaking for these bases that are NOT very prime!

On your ranges complete, I can't update anything on the web pages for base 24 without a # of k's remaining at the limits specified. For example on the Riesel side, it would be inaccurate to show the # of k's remaining at n=25K with a search limit of n=32.5K.

If you can do a quick count on your k's remaining at these limits, I'll go ahead and update both the ranges and k's remaining.

Thanks,
Gary

I'll now start the process of keeping at least some of my old promises, so for now, I'll reserve Sierp base 19 to n<=25K, and I'll do it this way:

1. PRP test up to n<=25K
2. Verify PRP tests
3. Remove k's from sievefile, and then maybe continue upwards towards n<=50K once further sieving has been added.

KEP!

Riesel base 31 is now at 90.8k, no additional primes to report.
Continuing...

Micha,

I didn't know if you saw the above post so I thought I'd repost it.

michaf · 2008-09-19, 18:09

Yep, I've seen it, and next time I'm physically near the machine, I will count :)
