Reg. strongly connected graph
I understood given a set of vertices, if every vertex can be reached from other vertices in that set then it is strongly connected (unless we can add vertex which support the same property).

I could not understand the mathematical notations very much. Please spend some time to explain the ':' part in it during the class --Kandhasamy Rajasekaran (discuss • contribs) 18:35, 8 January 2017 (UTC)
