Seifert fibering conjecture for non-integer surgeries

Let κ\kappa be a knot in S3S^3, and let a non-integer surgery mean surgery on κ\kappa with a non-integral slope. A surgery is Seifert fibred when the resulting 3-manifold admits a Seifert fibration.

Seifert fibering conjecture. If non-integer surgery on κ\kappa is Seifert fibred, then κ\kappa is a torus knot or a cable of a torus knot.

The conjecture concerns the classification of Seifert-fibred non-integer surgeries and is stated without a resolution status in the supplied text.
