Infinite Number of Primes Sat, Jul 22, 2017 02:00 CEST

The erroneous proof I hear most often is: Suppose $$P$$ is a finite set that contains all the primes, then $$p^* = 1 + \prod_{p \in P} p$$ is prime. Indeed, the flaw is that $$p^*$$ is not necessarily prime but rather must be a multiple of some prime not in $$P$$.
