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.

[QUOTE=unconnected;330369]k=29 has already been completed to n=400K
[URL]http://mersenneforum.org/showpost.php?p=327022&postcount=632[/URL] 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the various powers of bases 2 and 5 efforts (worked by other projects) about once every 36 months so it is slightly out of date.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300 is also out of date.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 
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=230K400K (base 1024) in it...a total of 2033 tests.

Sorry to burst your bubble here: Assuming an average nvalue in the file of n=3M base 2 and 4344 tests sieved to P=100P (100000T), the chance of prime was actually ~1314%. 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=230K400K base 1024), the actual chance of prime is ~6.3%.

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 nvalue. If you think I should cancel the this range or reduce the nvalue feel free to contact me.

*plonk* just a reminder for Gary, R751 update earlier

I won't be doing updates until next weekend.

Taking S627 to 25k.

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.

I will take S683, R611, R622, R688, R782, R833 to 200k.
