Please leave your opinion on these forms below!

(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.
