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, 1105 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.
Understanding the previous and next Carmichael Number helps in identifying numerical relationships and patterns. We explore both the preceding and succeeding values based on different property types.
