The consecutive-pair conjecture for order-three reflection groups

Let WW be a reflection group whose generators all have order three, let cWc\in W be a Coxeter element, and let TT be a longer reflection factorization of cc. A consecutive (t,t)(t,t) pair is a pair of adjacent equal reflections in a factorization. Consecutive-pair conjecture. The Hurwitz orbit of TT contains a reflection factorization with a consecutive (t,t)(t,t) pair. This is the proposed generalization of the corresponding lemmas for G4 and G5 and is intended to support the broader Hurwitz-transitivity conjecture; it is not proved here for the other order-three reflection groups discussed.
