The distribution of the number of bridges, $P\left(B\right)$ (bars), vs. number B, for reptating SAWs in the cases: $N=100$ and $N=200$, obtained by generating 5 ${10}^4$ configurations each. The continuous lines represent Gaussian fits, $P\left(B\right)=Aexp[$−(1/2)((B − $B_0{)/\sigma )}^2]$, yielding ($A=0.05$, $B_0=32.2$, $\sigma =7.84$) for $N=100$, and ($A=0.034$, $B_0=68.5$, $\sigma =11.84$) for $N=200$.
