Fermat's little theorem
the theorem that says `a^{p-1} \equiv 1 \pmod p` when `p` is prime and `p` does not divide
Core Idea
Fermat's little theorem is the theorem that says a^{p-1} \equiv 1 \pmod p when p is prime and p does not divide a. It usually makes the most sense alongside Euler's theorem, prime number, congruence.
