Baker–Wang's conjecture. For any non-planar ribbon graph, there exists a base point such that the rotor-routing action and the Bernardi action with the given base point are differe…

Let $G$ be a ribbon graph, with Bernardi torsor $\beta_v$ and rotor-routing torsor $r_v$ acting on its spanning trees for each vertex $v$. Bernardi–rotor-routing conjecture. If $G$…
