Abstract
We investigate the structure of the outer automorphism group of the Cuntz algebra and the closely related problem of conjugacy of MASAa in $\mathcal{O}_n$. In particular, we exhibit an uncountable family of MASAs, conjugate to the standard MASA $\mathcal{D}_n$ via Bogolubov automorphisms, that are not inner conjugate to $\mathcal{D}_n$.
