WebCyclotomic elds are an interesting laboratory for algebraic number theory because they are connected to fundamental problems - Fermat’s Last Theorem for example - and also … Over a finite field with a prime number p of elements, for any integer n that is not a multiple of p, the cyclotomic polynomial factorizes into irreducible polynomials of degree d, where is Euler's totient function and d is the multiplicative order of p modulo n. In particular, is irreducible if and only if p is a primitive root modulo n, that is, p does not divide n, and its multiplicative order modulo n is , the degree of .

In number theory, a cyclotomic field is a number field obtained by adjoining a complex root of unity to Q, the field of rational numbers.
