 2020-09-14, 04:19 #211 carpetpool     "Sam" Nov 2016 2×3×53 Posts Williams Primes base 3 I created a page for 10*3^n+1 so that Williams PP9 primes could be reused from there. There are also two new entries for these form of primes found by Ryan. They are included in the 10*3^n+1 page. I don't know if he is searching only even n values (Williams Primes) or odd n values as well. Thanks, I've corrected/extended those pages a little.

 2020-11-01, 05:50 #220 sweety439     Nov 2016 9C016 Posts Also, you can create page "Generalized Riesel prime 10 99" and "Generalized Proth prime 10 99" to make lists for "Williams prime MM 100" and "Williams primes MP 100" Also, you can reuse the "Riesel prime 255", "Riesel prime 511", "Riesel prime 1023", and "Riesel prime 2047" for "Williams prime MM 256", "Williams prime MM 512", "Williams prime MM 1024", and "Williams prime MM 2048", currently, all power-of-2 bases for the other three types of Williams primes are in the list, but for the "MM" type, only power-of-2 bases <= 128 are currently in the list.
