Also, Williams primes PP 327 (328*327^n+1) is checked to 300K, see post https://www.mersenneforum.org/showpo...postcount=2116

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.

80*81^5394+1, the second Williams MP prime base 81 (the first is 80*81^1+1)
Done for 80*3^n+1 instead. Last fiddled with by kar_bon on 20201019 at 15:03 Reason: done

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 powerof2 bases for the other three types of Williams primes are in the list, but for the "MM" type, only powerof2 bases <= 128 are currently in the list.
