Permutation polynomial
text:
In mathematics, a permutation polynomial is a polynomial that acts as a permutation of the elements of the ring, i.e. the map x ↦ g is a bijection. In case the ring is a finite field, the Dickson polynomials, which are closely related to the Chebyshev polynomials, provide examples. Over a finite field, every function, so in particular every permutation of the elements of that field, can be written as a polynomial function. In the case of finite rings Z/nZ, such polynomials have also been studied
