Equivalence of the Hurwitz transitivity and consecutive-pair conjectures

Let WW be a reflection group whose generators all have order three. Let cWc\in W be a Coxeter element. Let TT be a longer reflection factorization of cc. The Hurwitz transitivity conjecture asserts that reflection factorizations of cc are classified up to Hurwitz orbit by their multisets of conjugacy classes, while the consecutive-pair conjecture asserts that the Hurwitz orbit of TT contains a factorization with a consecutive (t,t)(t,t) pair. Equivalence conjecture. The Hurwitz transitivity conjecture and the consecutive-pair conjecture are logically equivalent. The paper presents this as a reduction for reflection groups with order-three generators; neither the general equivalence's constituent claims nor the resulting general transitivity statement is established there.
