 2008-01-30, 09:07 #1 gd_barnes     May 2007 Kansas; USA 1024410 Posts Sierp base 6 - team drive #3 We are starting Conjectures 'R Us (CRUS) team drive #3 for Sierp base 6 starting at n=30K and continuing until all k's have a prime or we just get tired of searching! Initially included in the drive were 50 of the remaining 56 k's that needed a prime. We have now found 45 primes so there are 11 k's remaining, all of which are in the drive. See the Sierp base 6 web page for the k's remaining. The file has been sieved for n=400K-1M. The sieve depth is P=130T. No more sieving will be needed for this range. Many thanks to Lennart for sieving P=25T-130T. We will be running the remainder of the drive on CRUS PRPnet server port 1400. The server will hand out the final range of n=700K-1M. Instructions for running a PRPnet server and download links can be found here. The info. specific to this server that needs to be entered into your prpclient.ini file is: server=G1400:100:1:noprimeleftbehind.net:1400 Server info.: CRUS PRPnet server (updated 2014-06-11 09:00 GMT): maintained by mdettweiler on gd_barnes machine Short identification: G1400 server: noprimeleftbehind.net port: 1400 Sierp base 6: 16 k's remaining to n=1M n-range: 700K-1M currently processing at n= (complete) Server summary: http://noprimeleftbehind.net:1400/all.html Primes found from the team drive plus all individual efforts for Sierp base 6 for n > 30K (red indicates top-5000 primes): Code: prime found by 139413*6^1279992+1 BOINC 33706*6^910462+1 mdettweiler 125098*6^896696+1 mdettweiler 31340*6^833096+1 mdettweiler 59506*6^780877+1 Lennart 10107*6^559967+1 Lennart 113966*6^511831+1 MyDogBuster 172257*6^349166+1 mdettweiler 121736*6^298935+1 mdettweiler 124221*6^278517+1 mdettweiler 51255*6^264988+1 mdettweiler 61340*6^262453+1 mdettweiler 26375*6^230349+1 Lennart 68195*6^215736+1 Flatlander 108527*6^185267+1 Lennart 74612*6^173463+1 Lennart 71301*6^172271+1 Lennart 145076*6^149946+1 Lennart 123285*6^147200+1 Lennart 157473*6^131124+1 MyDogBuster 36772*6^126672+1 MyDogBuster 118147*6^122688+1 MyDogBuster 98860*6^119849+1 MyDogBuster 72785*6^118347+1 Beyond 66520*6^96685+1 Beyond 135717*6^85064+1 Beyond 33676*6^82971+1 IronBits 125803*6^80211+1 IronBits 154797*6^77401+1 gd_barnes 90546*6^68012+1 mdettweiler 60017*6^64043+1 gd_barnes 129233*6^64027+1 gd_barnes 20721*6^63016+1 gd_barnes 98636*6^58201+1 gd_barnes 33298*6^57853+1 gd_barnes 151003*6^56371+1 gd_barnes 135500*6^53522+1 gd_barnes 27868*6^52504+1 gd_barnes 93241*6^50452+1 gd_barnes 86253*6^47459+1 gd_barnes 37815*6^39336+1 mdettweiler 18115*6^39155+1 gd_barnes 36028*6^37879+1 gd_barnes 137047*6^31754+1 gd_barnes 59606*6^30490+1 gd_barnes Status: Code: n-range tested by Status # of primes 1.5M-2M BOINC in progress 1M-1.5M BOINC complete 1 700K-1M PRPnet (G1400) complete 4 600K-700K rogue complete 0 540K-600K Lennart complete 1 480K-540K MyDogBuster complete 1 460K-480K Puzzle-Peter complete 0 400K-460K MyDogBuster complete 0 390K-400K Mini-Geek complete 0 325K-390K mdettweiler complete 1 324K-325K henryzz complete 0 322K-324K mdettweiler complete 0 316K-322K Batalov complete 0 314K-316K henryzz complete 0 240K-314K mdettweiler complete 4 228K-240K Lennart complete 1 214K-228K Flatlander complete 1 205K-214K Lennart complete 0 200K-205K Flatlander complete 0 166K-200K Lennart complete 3 154K-166K Flatlander complete 0 150K-154K Lennart complete 0 100K-150K PRPnet (G3000) complete 7 80K-100K LLRnet (IB6) complete 4 70K- 80K gd_barnes complete 1 67K- 70K mdettweiler complete 1 45K- 67K gd_barnes complete 10 38K- 45K mdettweiler complete 1 (plus 1 other) 30K- 38K gd_barnes complete 3 All sieved files have been tested.

Assuming a now-median k-value of k=90546 and the current 5000th place prime of 26267432109*2^333333-1 as of 3:10 AM EST US on 2/3/08, it would be at n=128958.

Of course it might be a smidge higher when we get there. It might actually be n=128960 or something.

Well, it looks like we have our work cut out for us, then!
