Prime Pages Achievable Forms?
 
I had just come up with two forms that are hard to find proven primes. Are there any journals to show that theses forms should be considered?:

Comment: Generalized Mersenne (Of the form a^n-(a-1)^n or (a^n-b^n)/(a-b))

Comment: Generalized/Dual Sierpinski/Riesel (Of the form b^n+/-c or k*b^n+/-c)

Please leave your opinion on these forms below! :smile:

(For the Prime Pages' top 20)

you can eliminate a lot of the last form listed with just simple thought and knowledge of arithmetic progressions. this along with necessary conditions can eliminate a lot. before you sieve with primes you can sieve within the progressions themselves.
