 > $\mathrm{with}\left(\mathrm{SpecialGraphs}\right):$
 > $G≔\mathrm{DoyleGraph}\left(\right)$
 ${G}{≔}{\mathrm{Graph 1: an undirected unweighted graph with 27 vertices and 54 edge\left(s\right)}}$ (1)
 > $\mathrm{GroupTheory}:-\mathrm{GroupOrder}\left(\mathrm{AutomorphismGroup}\left(G\right)\right)$
 ${54}$ (2)
 > $\mathrm{DrawGraph}\left(G\right)$
