(a) Mean exit time steps, $\langle T_{\mathrm{Exit}}\rangle$, to generate a reptation SAW configuration vs. N. The continuous line is a guide to the eyes, and the vertical lines are included for illustration, representing a standard deviation. The numerical data can be well fitted with the form, $\overline{T}=0.7exp\left(1.92N^{1/4}\right)$, for $N>20$. Averages over ${10}^4$ SAW configurations have been performed for the case $T_{\max }={10}^5$ steps and lattice size $L=2000$. (b) Reptating SAWs on a square lattice illustrated in the cases: $N=1000$ and $N=100$ monomers.
