Prove that there exist infinitely many primes p \equiv 3(\bmod ... | Filo

Prove that there are infinitely many primes congruent to 1 mod 4, by filling in the details of the following outline: (1) Prove: if an odd prime p and n ∈ℤ are such that n^2 ≡-1(p), then 4 |ϕ(p) [use a theorem in this section]. Why is it necessary to exclude the even prime here? (2) Therefore for n ∈ℤ, the odd prime divisors of n^2 1 are congruent to 1 mod 4 . (3) Now assume for contradiction's sake that there are only finitely many primes p1, …, pn congruent to 1 4 and consider the number (2 p1
