• As a Coequaliser. We have an isomorphism of sets
    \[ X/\mathord {\sim }^{\mathrm{eq}}_{R}\cong \text{CoEq}\webleft (R\hookrightarrow X\times X\stackrel{\stackrel{\text{pr}_{1}}{\rightarrow }}{\stackrel{\rightarrow }{\scriptsize \text{pr}_{2}}}X\webright ), \]

    where $\mathord {\sim }^{\mathrm{eq}}_{R}$ is the equivalence relation generated by $\mathord {\sim }_{R}$.
