 2017-03-26, 18:45 #301 edorajh     Oct 2003 Croatia 23·3·19 Posts Quick update on k=146921775. Found 6 more primes for n=50k-100k, so in total 102 primes for n=0-100k. Now working from n=1.29M up.

 2017-05-05, 14:00 #303 VBCurtis     "Curtis" Feb 2005 Riverside, CA 19·227 Posts You may. It has primes at n = 38, 182,374,430. See rieselprime.de, menu "riesel data". Someone checked it (and all k < 10,000) to n=10000 years ago to seed those web pages.

 2017-06-20, 03:42 #305 VBCurtis     "Curtis" Feb 2005 Riverside, CA 19·227 Posts Status for k>300 I've been testing: 2055 and 2085 are complete to 1025k, which I believe is the point where they joined one of the megabit drives. There had been a gap in the 607-620k range. I am not testing these, but was previously doing so in the under-1M range years ago, so I filled the gap when I discovered it. 2115 is complete to 1.56M. 2145 complete to 1.36M. 2175 complete to 1.33M. All 5 of these had a gap from 607k to 620k, and filling that gap produced one prime (posted in the small primes thread, 2115@607390). 405 is complete to 1.72M. 443 is complete to 3.31M.
