Eccentric graph

Eccentric graph --- граф эксцентриситетов.

A graph [math]\displaystyle{ G }[/math] is an eccentric graph if every vertex of [math]\displaystyle{ G }[/math] is an eccentric vertex. If [math]\displaystyle{ G }[/math] is self-centered, then [math]\displaystyle{ G }[/math] is an eccentric graph.
