Motivated by the notion of extremal vertex operator algebras, we investigate cyclic orbifolds of vertex operator algebras coming from extremal even self-dual lattices in d=48 and d=72. In this way we construct about one hundred new examples of holomorphic VOAs with a small number of low weight states.
