In the mathematical discipline of graph theory, the (m,n)-lollipop graph is a special type of graph consisting of a complete graph (clique) on m vertices and a path graph on n vertices, connected with a bridge.
The special case of the (2n/3,n/3)-lollipop graphs are known as graphs which achieve the maximum possible hitting time, cover time and commute time.
