Liebeck–Shalev conjecture on epimorphic homomorphisms from Fuchsian groups

Let Γ\Gamma be a Fuchsian group, and let GG be a finite simple classical group. A randomly chosen homomorphism in Hom(Γ,G){\rm Hom}(\Gamma,G) is an epimorphism with a probability that may depend on GG. Liebeck–Shalev's conjecture. For any Fuchsian group Γ\Gamma there is an integer f(Γ)f(\Gamma) such that, if GG has rank at least f(Γ)f(\Gamma), then the probability that a randomly chosen homomorphism in Hom(Γ,G){\rm Hom}(\Gamma,G) is an epimorphism tends to 11 as G|G|\rightarrow\infty.

This extends asymptotic epimorphism results for Fuchsian groups and large finite simple groups; the source explicitly says that the conjecture remains open for arbitrary Fuchsian groups.
