WebWe use Fermat's little theorem to test whether a polynomial is irreducible or not. WebA polynomial of degree over the finite field GF (2) (i.e., with coefficients either 0 or 1) is primitive if it has polynomial order . For example, has order 3 since (2) (3) (4) Plugging …
Webcharacteristic is two, and F = Z/2Z = GF(2). T(x) is irreducible if it has no nontrivial factors. If 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 WebFrom the following tables all irreducible polynomials of degree 16 or less over GF(2) can be found, and certain of their properties and relations among them are given. A primitive …
