Check if 127 is Carmichael Number?

A Carmichael number is a composite number that behaves like a prime in certain conditions. Specifically, for any integer a that is coprime to n, the equation a^(n-1) ≡ 1 (mod n) holds true, similar to prime numbers per Fermat's little theorem. However, Carmichael numbers are not prime. For example, 127 is Carmichael number because it satisfies Fermat's little theorem for every integer a coprime to it, even though it is composite. Carmichael numbers are significant in number theory because they can fool primality tests, revealing flaws in certain algorithms.
