Let G be an irreducible collineation group of a finite projective plane π of even order n ≡ 0 mod 4. Our goal is to determine the structure of G under the hypothesis that G fixes a hyperoval Ω of π. We assume |G| ≡ 0 mod 4. If G has no involutory elation, then G = O(G) S 2 with a cyclic Sylow 2-subg
