Recently, I was studying the knot group and I want to learn some more material about it (e.g. its representations).
"Knots" by Burde and Zieschang discusses some material but it is not entirely covered. Also, Rolfsen talks about the fundamental group and Wirtinger presentation but not about the representations in the symmetric group or the dihedral group.
So, what is a good reference for the knot group, its subgroups and its representations (and related topics to the knot groups)?
