In this paper, they mention that they used I which is the inverse of the finite field GF ( 2 3) with the irreducible polynomial x 3 + x + 1. This inverse corresponds to the monomial x ↦ x 6. WebThe irreducible polynomials overF whose zero sets are invariant under this action ofC are the irreducible factors of Ore's psi-polynomials ψc,k fork=0,1,2... We study the factorization of these polynomials into components. A component is defined as the product of all monic, irreducible factors of a fixed degree.

WebThe monic polynomials of degree 2 are x^2, x^2+1, x^2+x, and x^2+x+1. Since x^2, x^2+1, x^2+x all have roots in F_2, they can be written as products of x and x+1. Hence x^2+x+1 is the only irreducible polynomial of degree 2 in F_2 [x]. For degree 3, the polynomial p (x) must not have any linear factors.
