Post 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.
