Gap critical exponents for bond percolation on 2D square lattice systems. (a) and (b), $\overline{\Delta }\left(L\right)$ and ${\chi }_{\Delta }$ as functions of $L$. (c) and (d), log–log plot of the percolation threshold ${\overline{r}}_c\left(L\right)$ and ${\chi }_{\Delta }$ versus $L$. (e) and (f). The power-law relations of $\overline{S_c}\left(L\right)$ and ${\chi }_{S_c}$ with $L$. Inset in (c) shows the log–log plot of $r_c\left(\infty \right)-{\overline{r}}_c\left(L\right)$ as a function of $L$.
