Irreducible polynomial finite field
http://mathonline.wikidot.com/reducible-and-irreducible-polynomials-over-a-field Every polynomial over a field F may be factored into a product of a non-zero constant and a finite number of irreducible (over F) polynomials. This decomposition is unique up to the order of the factors and the multiplication of the factors by non-zero constants whose product is 1. Over a unique factorization domain the same theorem is true, but is more accurately formulated by using the notion of primitive polynomial. A primitive polynomial is a polynomial over a unique fact…

WebLet Fq denote the finite field of order q — pn , where p is prime and « > 1. The multiplicative group F* of nonzero elements of Fq is cyclic and a generator of F* is called a primitive element. Moreover, a monic irreducible polynomial whose roots are primitive elements is called a primitive polynomial.
