Report top-5000 primes for all k<=1001Please report all top-5000 primes for k<=1001 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="http://www.rieselprime.de/Data/00300.htm"]here[/URL]. It includes all known n-ranges starting at n=1 and will be updated as we complete n-ranges 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 top-5000 prime: Go to [URL]http://primes.utm.edu/primes/home.php[/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 commas but without quotes) for the project and sieving software. [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'.

Prime to get us started...It's not quite top-5000 material but here's the first one to get us started:
745*2^333239-1 is prime (100318 digits) This is pretty good for this k-value. Even thought it's relatively average weight, up to n=260K, its previous highest prime to date was at n=75771. Gary |

here we go:
747*2^333709-1 is prime! (100460 digits) |

[quote=kar_bon;123496]here we go:
747*2^333709-1 is prime! (100460 digits)[/quote] :cool: Bring it on! I want it noted that Prime Search has 53 top-5000 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. Gary |

495*2^338804-1 is prime!
639*2^343683-1 is prime! 639*2^343305-1 is prime! 489*2^343303-1 is prime! |

[quote=em99010pepe;124493]495*2^338804-1 is prime![/quote]
FINALLY! A top-5000 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! |

[quote=em99010pepe;124732]639*2^343305-1 is prime!
489*2^343303-1 is prime![/quote] 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*2^321410-1 is prime Gary |

[quote=em99010pepe;124835]From LLRNet
693*2^321959-1 is prime! (IronBits)[/quote] [quote=em99010pepe;124838]From LLRNet (IronBits) 795*2^322014-1 is prime! EDIT: Primes from LLRNet were double-checked.[/quote] Yay! Our first LLRnet primes! And in such close succession! :w00t: |

Wow, I'm offline for 10 hours to get some rest and I come back and we have 5 new primes including 2 top-5000's!!
:george: |

All primes so far found by LLRNet have been double-checked by me using LLR 3.7.1c on an AMD 64 3000+ (2GHz).

Yes he does.
user=Free-DC_em99010pepe [02/13/08 17:07:35] 573*2^350426-1 is prime! With only one core on LLRnet!!! 441*2^323913-1 is prime! (Confirmed) |
