is how some of the things on these forums are connected like:

- mersenne prime exponents linking to cunningham chains of the first kind (as well as other primes if you don't accept length 1 chains if you accept that the following hold) a mersenne prime exponent>3 can only be the last member of a cunningham chain of the first kind or the first term in a chain that starts with a prime p=4n+1, or a 1 chain length prime of form 4n+3.
- the Lucas Lehmer test in reduced form is similar to TF
- okay not sure of what else to put here can't think of any more right now even though I could say maybe some computer science things.
