Abstract
Let \( \mathbb{F} \) denote the infinite field that is the union of all extensions of GF(2) of odd degree. Let q = 2m and let \( {\mathbb{F}_{Q}} = GF(2{q^{2}}) \). We provide a simple proof of the permutation property of the polynomials x 2q+1 + x 3 +x on \( {\mathbb{F}_{Q}} \) for each m by viewing each member of the class as the action of a simply defined permutation of \( \mathbb{F} \).
