b17:
yeah, great timing: two hours ago, the sieving till 1T for the next range (n 100,000 - 1,000,000) was finished, and now PRP till n = 100,000 is done.
Still no prime :(

b18:
PRP still around n = 150,000 - I am sieving at the moment.

Of course, I intend to start with my already reserved number. k=16734 base=4. :)

Jasong,

Apparently we don't have any sieved files for k=16734. We're you still planning to test it?

Jean Penne effectively tested it to n=131022 base 4 with the Riesel base 2 odd-n effort for k=8367.

I missed the connection there in showing the testing limits on the web pages. I'm correcting those now.

Edit: If still planning to test it, do you have an idea of how far are you planning to take it?

Jean,

As Jasong begins testing k=16734 base 4 above n=131022, you can update your corresponding test ranges on the Riesel base 2 odd-n effort for k=8367.

Sierpinski Base 6 k=168610 has been tested up to n=100K, no primes found. I'm releasing this k. lresults for n=30K-100K are attached.

Status report on Sierp. Base 6 k=172257: currently at about 80.9K, still working on it.

594*27^36624-1 is prime.

found PRP by LLR, proven with pfgw. I won't continue that range.

Willem.

Siemelink · 2008-01-23, 19:34

I've completed 706*27^n-1 and 194 & 404*23^n-1 for all n until 100,000. No primes were found. I won't continue these pairs.

Reserving the following Sierp. Base 6 k's for LLRnet:
154797
157473
166754
LLRnet will take these three k's up to n=100K (the end of the sieve files available).

Never mind, we're not reserving these k's for LLRnet after all.

update: sierpinski base 31 is at n=1320 ... 7707 k without primes

i'm still working on it !

Go Tnerual go! 7707 k's...wow. Good luck!
