Report top5000 primes for all k<=1001
Please report all top5000 primes for k<=1001 in this thread.
Kar_bon has a list of all primes found and searchranges previously completed on the k's that we will be searching here. It includes all known nranges starting at n=1 and will be updated as we complete nranges and find primes. For 300<k<=1001 and n>=260K, the ranges and primes will be shown in the team drives here. Instructions for submitting a top5000 prime: Go to http://primes.utm.edu/primes/home.php. Step 1: For people who have not submitted top5000 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 proveraccount' 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 proveraccounts', 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 ProofCode' and press enter. 5. If necessary in the little popup 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 commas but without quotes) for the project and sieving software. [If you did an individualk 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 proofcode', 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 popup box, type in your user name (prover account) and password and press enter. 5. You should see a big freeform 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'.

Prime to get us started...
It's not quite top5000 material but here's the first one to get us started:
745*2^3332391 is prime (100318 digits) This is pretty good for this kvalue. Even thought it's relatively average weight, up to n=260K, its previous highest prime to date was at n=75771. Gary

Bring it on!
I want it noted that Prime Search has 53 top5000 primes (now 54) at the beginning of this project and is in 9th place. We should be able to fairly quickly move up into 6th place, which is the old 15k project that has 82 primes. Edit: It's kind of interesting that our first two primes were for k=745 and k=747.

FINALLY! A top5000 prime for 400<k< 500. There are just a few less k's in the 400's than the others due to prior reservations and searches but it was still surprising how long it took to find one.
2 more to move into 7th place all alone!

Great run Carlos! That's amazing on k=639. I cannot recall primes so close together on a single k at such a high n and such a low k. (only n=378 difference)
In the mean time, another 'smaller' one: 533*2^3214101 is prime Gary
