- Let $Σ_b$ be a compact Riemann surface of genus $b \geq 2$ and let $\mathsf{P}_2(Σ_b)=π_1(Σ_b \times Σ_b - Δ)$ be the corresponding pure braid group on two strands. A finite quotient $φ\colon \mathsf{P}_2(Σ_b) \to G$ is called "admissible" if $φ$ does not factor through $π_1(Σ_b \times Σ_b)$. In this work we classify all admissible quotients of $\mathsf{P}_2(Σ_b)$ such that $|G| \leq 127$.
