In this paper we give an explicit and constructive description of the pairs (μ, λ) of elements in the symmetric groupSnwhich can be realized as the image of the meridian-longitude pair of some knotKin the 3-sphereS3under a representation π1(S3−K) →Sn. The result is applied to give an otherwise nonobvious restriction on the numbers of branch curves of a branched covering ofS3, answering a question of R. Fox and K. Perko.
