Hurwitz-orbit conjecture for factorizations in well-generated complex reflection groups

Let WW be a well-generated finite complex reflection group, let cc be a Coxeter element of WW, and consider factorizations of cc into reflections. Two such reflection factorizations share the same multiset of conjugacy classes when the multisets of conjugacy classes of their factors coincide. Hurwitz-orbit conjecture. Two reflection factorizations of cc lie in the same Hurwitz orbit if and only if they share the same multiset of conjugacy classes. This is presented as a verbatim generalization of the theorem for finite real reflection groups; its status for well-generated finite complex reflection groups is not resolved in the supplied text.
