Upper bounds of orders of automorphism groups of leafless metric graphs

Figures & data

Fig. 1 The left graph is $G_{\text{banana},2}$, the center graph is $G_{\text{bouquet},3}$ and the right graph is $G_{\text{lollipop},4}$. Black dots (resp. lines) stand for vertices (resp. edges).

Fig. 2 We call the left graph H₁ and the right graph H₂. Black dots (resp. lines) stand for vertices (resp. edges).

Fig. 3 We call the graph H. Black dots (resp. lines) stand for vertices (resp. edges).
