WebConsider the field GF(16 = 24). The polynomial x4 + x3 + 1 has coefficients in GF(2) and is irreducible over that field. Let α be a primitive element of GF(16) which is a root of this polynomial. Since α is primitive, it has order 15 in GF(16)*. Because 24 ≡ 1 mod 15, we have r = 3 and by the last theorem α, α2, α2 2 and α2 3 WebJun 5, 2012 · Summary. The theory of polynomials over finite fields is important for investigating the algebraic structure of finite fields as well as for many applications. …

Primitive polynomials are also irreducible polynomials. For any … WebIn this paper, we construct two families of linear codes with a few weights based on special polynomials over finite fields. The first family of linear codes are extended primitive cyclic codes which are affine-invariant. The second family of linear codes are reducible cyclic codes. The parameters of these codes and their duals are determined. monoii スケボー

Those constructions require you to find the minimal polynomial of α d for some d. … monolith partners モノリスパートナーズIn finite field theory, a branch of mathematics, a primitive polynomial is the minimal polynomial of a primitive element of the finite field GF(p ). This means that a polynomial F(X) of degree m with coefficients in GF(p) = Z/pZ is a primitive polynomial if it is monic and has a root α in GF(p ) such that See more • 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 See more A useful class of primitive polynomials is the primitive trinomials, those having only three nonzero terms: x + x + 1. Their simplicity makes for … See more Field element representation Primitive polynomials can be used to represent the elements of a finite field.
