WebJan 1, 2015 · For example, we can use x^ {m+1} + 1 for P ( x) if the m -th degree All One Polynomial (AOP) is irreducible according to the following formula over GF (2): \begin {aligned} x^ {m+1} + 1 = (x+1) (x^m+x^ {m-1}+ \dots +1), \end {aligned} (1) where the polynomial x^m+x^ {m-1}+ \dots +1 is called the m -th degree AOP. WebFor polynomials over GF (2), where 2r − 1 is a Mersenne prime, a polynomial of degree r is primitive if and only if it is irreducible. (Given an irreducible polynomial, it is not primitive only if the period of x is a non-trivial factor of 2r − 1. Primes have no non-trivial factors.)
