     \item For each of the following graphs, find $\vertexConnectivity{G}$, $\edgeConnectivity{G}$, $\minDegree{G}$, $\eccentricity{v}$ of each vertex $v \in V(G)$, $\graphRadius{G}$, $\graphDiameter{G}$, $\graphCenter{G}$.
     Find Euler path, Euler circuit, and Hamiltonian cycle, if they exist.
-    In addition, find maximum clique $Q \subseteq V$, maximum stable set $S \subseteq V$, maximum matching $M \subseteq E$, minimum dominating set $D \subseteq V$, minimum dominating set $D \subseteq V$, minimum vertex cover $R \subseteq V$, minimum edge cover $F \subseteq E$ of $G$.
