Hyperovals of H(3,q2) when q is even

Lookup NU author(s): Dr Antonio Cossidente, Dr Oli King



For even q, a group G isomorphic to PSL(2,q) stabilizes a Baer conic inside a symplectic subquadrangle W(3,q) of H(3,q^2). In this paper the action of G on points and lines of H(3,q^2) is investigated. A construction is given of an infinite family of hyperovals of size 2(q^3-q) of H(3,q^2), with each hyperoval having the property that its automorphism group contains G. Finally it is shown that the hyperovals constructed are not isomorphic to known hyperovals.
