WebFeb 20, 2024 · The polynomial x^8 + x^4 + x^3 + x^1 is not irreducible: x is obviously a factor!. My bets are on a confusion with x^8 + x^4 + x^3 + x + 1, which is the lexicographically first irreducible polynomial of degree 8. After we correct the polynomial, GF (2 8) is a field in which every element is its own opposite. 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...
