Abstract
Developing novel classes of permutation polynomials(PPs) has become a prominent focus in recent mathematical research. We introduce new classes of permutation pentanomials defined on 𝔽52n through the strategic selection of coefficients expressed as xr h(xq–1), where q = 5n. Over nine distinct classes are identified, with further generalizations achieved by varying the exponent r.
