    Indirect proof of Infinate number of primes

    IN class we derived the following expressionto express "There are an infinate number of primes" using predicates prime(x) : x is a prime and g(x, y): x > y There exists a "z" in N, prime(z) and [for all "x" in N , (prime(x) --> there exists a "y" in N, (prime(y) and g( y, x)))] I believe...
