Examples of non-isomorphic graphs on N vertices which are transient amplifiers of death–Birth updating. a–d: $N=14$, which have maximum degree $\Delta (\mathcal{G})=6$. e–h: $N=20$, which have maximum degree $\Delta (\mathcal{G})=9$. i–l: $N=26$, which have maximum degree $\Delta (\mathcal{G})=12$ except j, which has $\Delta (\mathcal{G})=13$. The values of the effective population size $N_{\text{eff}}$, the minimum degree $\delta (\mathcal{G})$, the mean degree $\overline{k}$ and the algebraic connectivity ${\lambda }_2$ are
