This is a very general question: let $f:X\to \mathbb P^1$ be a branched cover of compact Riemann surfaces, where $X\subset \mathbb P^n\times \mathbb P^1$ and $f$ is the natural projection. For any reguler $y\in \mathbb P^1$, the fiber $f^{-1}(y)$ contains $d$ points. We call the $f$ is solvable if there is a formula for these $d$ points in terms of $y$.
I want to know that, if the following two things are related?
(i) The cover of $f$ is Galois (i.e. normal);
(ii) $f$ is solvable, as defined above.
