I'm considering finite index abelian (regular) covering of link complement:
$ X \rightarrow S^3\backslash L$$$ X \rightarrow S^3\setminus L$$
where $L$ is a minimally twisted chain link.
I'm interested in covering space. Can we compute its cohomology (or maybe fundamental group) in terms of $S^3\backslash L$$S^3\setminus L$? Is it true that $X$ is link complement? I would appreciate any helpful tip on this.
