In this paper we propose the study of the hyperbolic cover $\tilde{W}$ of an elliptic Weyl group. For $\tilde{c}$ a Coxeter transformation in $\tilde{W}$ we prove Hurwitz transitivity of the braid group on the set of reduced reflection factorizations of $\tilde{c}$, which then enables us to establish for a weighted projective line $\mathbb{X}$ of tubular type an order preserving bijection between the poset of thick subcategories of $\mathrm{coh}(\mathbb{X})$ generated by an exceptional sequence and the interval poset $[\mathrm{id}, \tilde{c}]$ ordered by the absolute order. |
