Orthogonal Dual Hyperovals, Symplectic Spreads and Orthogonal SpreadsAbstract: Orthogonal spreads in orthogonal spaces of type $V^+(2n+2,2)$ produce large numbers of rank $n$ dual hyperovals in orthogonal spaces of type $V^+(2n,2)$. The construction resembles the method for obtaining symplectic spreads in $V(2n,q)$ from orthogonal spreads in $V^+(2n+2,q)$ when $q$ is even.
