Asymmetric knots with two cyclic surgeries

The cyclic fillings of a hyperbolic manifold are of considerable interest. John Berge constructed a list of knots in S3 that admit a non-trivial cyclic filling and the Berge conjecture states that this list is complete. A consequence of the Berge Conjecture is that all such knot complements admit an order two symmetry. While the natural generalization of the Berge Conjecture still provides a list of hyperbolic manifolds with two cyclic fillings, we show such a list is incomplete. Finally, this provides examples of L-spaces which are not the double branched covers of knots in S3.
