Structure and Randomness in the Prime Numbers
... Theorem 1 (Euclid’s Theorem). There are infinitely many primes. In particular, given any k, there exists a prime with at least k digits. But there is no known quick and deterministic way to locate such a prime! (Here, “quick” means “computable in a time which is polynomial in k”.) In particular, ther ...

... For all other positive integers the value of Carmichael’s function is the least common multiple of all the dividing primes raised to the appropriate powers (e.g., to calculate ψ(504) we’d reckon ψ(23 ), ψ(32 ) and ψ(7) and find the LCM of these). Sequence A002322 in Sloane’s OEIS gives values of ψ(n ...

... called Mersenne primes. A Mersenne prime is a prime number that can be written as 2p - 1, where p is some other prime number. For example, when p = 2, then 22 - 1 = 4 - 1 = 3, so 3 is a Mersenne prime. Every perfect number that has been discovered so far has a Mersenne prime as one of its factors. C ...
