Several classes of permutation polynomials with given form over [Formula: see text] were recently proposed by Tu, Zeng, Li and Helleseth. In this paper, continuing their work, we present more permutation polynomials of the form [Formula: see text] over the finite field [Formula: see text] where [Formula: see text] is a linearized polynomial with coefficients in [Formula: see text].
