WebWe describe an algorithm which computes all subfields of an effectively given finite algebraic extension. Although the base field can be arbitrary, we focus our attention on the rationals. WebIf T(x) is irreducible of degree d, then [Gauss] x2d = x mod T(x). Thus T(x) divides the polynomial Pd(x) = x2 d −x. In fact, P d(x) is the product of all irreducible polynomials of degree m, where m runs over the divisors of d. Thus, the number of irreducible polynomials of degree d is 2d d + O 2d/2 d!.

• Because all minimal polynomials are irreducible, all primitive polynomials are also irreducible. • A primitive polynomial must have a non-zero constant term, for otherwise it will be divisible by x. Over GF(2), x + 1 is a primitive polynomial and all other primitive polynomials have an odd number of terms, since any polynomial mod 2 with an even number of terms is divisible by x + 1 (it has 1 as a root). WebThe elements of GF (2 2) are. where α is a zero of the primitive polynomial f (x) = 1 + x + x2. Since α satisfies the equation. Multiplication in this field is performed according to Eq. …
