Two new classes of permutation polynomials over finite fields are presented: (i) [Formula: see text] over [Formula: see text] where e is a positive even integer; (ii) gn,p(x)=∑np⩽l⩽np−1nl(ln−l(p−1))×xn−l(p−1)over [Formula: see text] where e is a positive integer such that e≡0(mod 2) if p=2, and n=(p−1)pm+p0e+p1e+⋯+p(p−1)e, (m−1,e)=1. The permutation polynomial in (i) answers an open question about reversed Dickson polynomials.
