The cyclotomic polynomials are monic polynomials with integer coefficients that are irreducible over the field of the rational numbers. Except for n equal to 1 or 2, they are palindromics of even degree. The degree of , or in other words the number of nth primitive roots of unity, is , where is Euler's totient function. Webv. t. e. In mathematics, the ring of integers of an algebraic number field is the ring of all algebraic integers contained in . [1] An algebraic integer is a root of a monic polynomial with integer coefficients: . [2] This ring is often denoted by or .
