With help from Lennart, I have collected the n to be tested for R1024 for n up to 400000 (n=4000000 base 2). I'm too busy with R151 to spend time on it right now, but if someone else is interested, here you go. There are 4344 tests in this file. Presuming I've calculated correctly, there is a 50% chance that a prime will be found amongst these tests.

And k=37 now @ 229K (info from rieselprime.de).[/QUOTE]

The CRUS pages have k=29 at 339K and k=37 (74) at 240K. I generally try to update the various powers of bases 2 and 5 efforts (worked by other projects) about once every 3-6 months so it is slightly out of date. Rieselprime.org for k<300 is also out of date. Per 15k.org, k=29 is at 400K and k=37 (74) is at 230K base 1024. I'm not sure where I got that k=37 was at 240K.

So officially for our R1024 purposes:
k=29 is at n=400K
k=37 (74) is at n=230K

 gd_barnes 2013-02-21 21:49

I have updated the CRUS pages to show the current search depth for R1024. I have also provided a link to the R1024 sieve file on the reservations page. I have sorted the file by n and removed all tests that have already been done base 2 so it should only have k=37 for n=230K-400K (base 1024) in it...a total of 2033 tests.

Sorry to burst your bubble here:

Assuming an average n-value in the file of n=3M base 2 and 4344 tests sieved to P=100P (100000T), the chance of prime was actually ~13-14%.

Now that we know that there are only 2033 pairs remaining to be tested in this range at an average n=~3.15M (k=37 for n=230K-400K base 1024), the actual chance of prime is ~6.3%.

Sorry, you're correct. For some reason I was thinking 1024=2^8 and 2^10 at the same time. With fewer pairs, it will take a lot less time for someone to test.

I don't test 24/7. I'd like to keep this range, because there are plenty ranges and conjectures which are free to be reserved by other contributors and I don't see a reason why I should cancel this conjecture. I can cut the range down to a smaller n-value. If you think I should cancel the this range or reduce the n-value feel free to contact me.

Taking R693, currently at 5.6k :P
Update on (S331?), currently at 14.7k.
Both on different computers, the 331 was as of this morning.

R866

Watched these forums for a long time and finally decided its time to get involved with some of these conjectures.
I'll try taking R866 up to 200k

R866

Think I've had a large case of beginners luck!

8*866^108590-1 is prime.

Last k eliminated so R866 is now proven

 firejuggler 2013-07-08 14:50

nice job rob, one more bite the dust! and it make in the top 5000 largest primes. In the 3400-3500 top range.

Beginners luck or not, it's nice to eliminate another pesky 1ker.:banana:
It is also eligible for the Top5000 list.

Congrats on your first top 5000 prime! :smile:

Request: Can you Email Chris Caldwell at [EMAIL="caldwell@utm.edu"]caldwell@utm.edu[/EMAIL] and ask him to add the project CRUS to your proof code? Thanks.

I finished up to n=8073

 firejuggler 2013-07-09 21:43

Ok, i'll *finish* R751 upto 10k.
I find 532 sequences left. Are we in agreement Gary?

Yep. We are in agreement. I have now updated the pages for the new status including a link to an updated sieve file with all the primed k's removed.

Taking S627 to 25k.

 rogue 2013-07-28 23:09

Take S803, S816, S844, S850, S853, S930, S953, and S1004 to n=200000. They need more sieving, so I pulled eight cores off of S6 to focus on that. Hopefully they won't need too much extra sieving.

Since my range of S6 will be done by Friday (with no primes :sad:), I will take S701, S702, S706, S736, S737, S740, S778, and S780. With the 20 single k bases I have reserved, I should find a few primes.
