 2008-01-08, 09:07 #1 gd_barnes     May 2007 Kansas; USA 23×3×52×17 Posts Riesel base 16 - team drive #2 We are starting Conjectures 'R Us (CRUS) team drive #2 for Riesel base 16 starting at n=25K and continuing until all k's have a prime. Included in the drive are 12 of the remaining 17 k's that need a prime. A link to a sieved file is below. As we find primes, we will remove candidates from the files. The file has been sieved for n=250K-500K and no more sieving is needed. The sieve depth is P=70T. As we find primes, we'll remove k's from the file for higher n-ranges. We are posting one large file that people can cut individual reservations out of. This should give people more flexibility with their ranges. Please reserve a range that will take no longer than ~4-6 weeks. IMPORTANT: Please reserve in multiples of n=2000 and begin your range with n=xxx001 and end with n=xxx000 to avoid missing or duplicating tests. Please post all primes, reservations, and statuses in this thread instead of using other multiple threads. We'll be checking this thread frequently for primes so that we can quickly get candidates removed from the file that no longer need to be tested. Here is a breakdown of the 17 k's that are remaining: 12 in the team drive for n=200K-500K. 3 reserved for PrimeGrid and searched to n>1M with the Riesel base 2 conjecture effort. 1 reserved for base 4 and searched to n>1M. 1 unreserved for base 4 and searched to n=500K. Below are primes found from the team drive plus all individual efforts for Riesel base 16 for n > 25K. Red indicates top-5000 primes. Primes: Code: prime found by 3620*16^435506-1 KEP 7673*16^366247-1 KEP 33863*16^236436-1 Mini-Geek 6852*16^216571-1 MyDogBuster 2993*16^211161-1 antiroach 15068*16^204680-1 unconnected 13854*16^185870-1 gd_barnes 19413*16^181080-1 mdettweiler 1478*16^147920-1 gd_barnes 33723*16^102191-1 gd_barnes 17798*16^97394-1 kar_bon 15458*16^81157-1 tnerual 16734*16^78426-1 gd_barnes 5307*16^76522-1 tnerual 27833*16^57892-1 kar_bon 18957*16^50221-1 kar_bon 8702*16^41326-1 kar_bon 17735*16^38991-1 kar_bon Status: Code: n-range tested by Status # of primes 320K-500K KEP complete 2 260K-320K MyDogBuster complete 0 220K-260K Mini-Geek complete 1 216K-220K MyDogBuster complete 1 210K-216K antiroach complete 1 200K-210K unconnected complete 1 190K-200K gd_barnes complete 0 170K-190K mdettweiler complete 1 (plus 1 other) 156K-170K MyDogBuster complete 0 154K-156K Flatlander complete 0 150K-154K MyDogBuster complete 0 130K-150K gd_barnes complete 1 126K-130K mdettweiler complete 0 110K-126K gd_barnes complete 0 87.5K-110K LLRNet complete 2 85K-87.5K kar_bon complete 0 74K-85K tnerual complete 2 (plus 1 other) 71K-74K mdettweiler complete 0 25K-71K kar_bon complete 4 All sieved files have been tested. Eventually we will begin sieving a higher n-range. All primes now found will be top-5000 primes so have fun and take down some k's!
