Report top-5000 primes for k=1003-3000
Please report all top-5000 primes for k=1003-3000 in this thread.

Kar_bon has a list of all primes found and search-ranges previously completed on the k's that we will be searching [URL=""]here for k=1003-2000[/URL] and [URL=""]here for k=2000-3000[/URL]. It includes all known n-ranges starting at n=1 and will be updated as we complete ranges and find primes.

Instructions for submitting a top-5000 prime:

Go to [URL=""][COLOR=#810081][/COLOR][/URL].

Step 1: For people who have not submitted top-5000 primes previously, create a prover account:
1. Select 'Submit' on the lower left side under 'Join in'.
2. Select the 'click here to create a prover-account' link in the middle of the page.
3. Fill out the form and submit it. You will be assigned a prover account.

Step 2: Create a proof code:
1. Go to the home page in the link above and select 'Index' on the left side under 'Provers'.
2. Next to 'search prover-accounts', type yours and press enter.
3. Click on your prover account (there may be one or several) and press enter.
4. Towards the bottom, click on 'Create a New Proof-Code' and press enter.
5. If necessary in the little pop-up box, type in your user name (prover account) and password and press enter.
6. You should now have a list of proof programs. Select LLR.
7. In the space below all the programs that says "none", type "NPLB, srsieve, psieve" (WITH the comma but without quotes) for the project and sieving software. (Obviously if you did an individual-k search on your own, then the software may vary.)
8. You should now have a new proof code and can submit the prime. Example...L442.

Step 3: Submit the prime:
1. Go to the home page in the link above and select 'Index' on the left side under 'Provers'.
2. Next to 'search proof-code', type your new code from step 2 and press enter.
3. Towards the bottom, next to 'Submit primes using this code as', click on your name (prover account) and press enter.
4. If necessary in the little pop-up box, type in your user name (prover account) and password and press enter.
5. You should see a big free-form box. Type in your prime (no spaces needed) and click 'Press here to submit these prime(s)'.
6. A verification screen will come up. If the prime is correct, click 'Press here to complete submission'.

I have deleted some smaller primes and some posts related to the inadvertant restart of the 8th drive from this thread, changed it's title slightly, and edited the 1st post to make it for n>200K primes only.

1539*2^352111-1 is a confirmed prime

MyDogBuster 2009-01-18 02:09

1943*2^352182-1 is prime

Note: This in only 271 digits higher than #5000. We are just barely ahead of the wave, 4962 place

I suppose it's appropriate that this is a confirmed prime since I found it in my first 200-300 tests of port 8000:

1567*2^352397-1 is confirmed prime

It looks like Chris has a new one though. That's 2 new and 2 confirmed primes in ~12 hours. Now this is what I would call fun! :-)

All times are UTC. The time now is 18:27.
