Generalized Kauffman–Harary conjecture

Let KK be a prime alternating knot, and let DD be an alternating diagram of KK without nugatory crossings, so that DD is a minimal diagram. Let XK(2)X^{(2)}_K denote the double cover of S3S^3 branched along KK. Generalized Kauffman–Harary conjecture. Different arcs of DD represent different elements of

H1(XK(2),Z).H_1(X^{(2)}_K,\mathbb{Z}).

This conjecture concerns the relationship between minimal alternating knot diagrams and the first homology of the double branched cover. The supplied text does not state whether the conjecture is open or resolved.
