    • … The diameter of a graph is the maximum eccentricity of any vertex in the graph. That is, it is the greatest distance between any pair of vertices. To find the diameter of a graph, first find the shortest path between each pair of vertices. The greatest length of any of these paths is the diameter of the graph.

    • QUOTE: The length max_(u,v)d(u,v) of the "longest shortest path" (i.e., the longest graph geodesic) between any two graph vertices (u,v) of a graph, where d(u,v) is a graph distance. In other words, a graph's diameter is the largest number of vertices which must be traversed in order to travel from one vertex to another when paths which backtrack, detour, or loop are excluded from consideration. The above random graphs on 10 vertices have diameters 3, 4, 5, and 7, respectively.

      The diameter of a graph may be computed using Diameter[g] in the Mathematica package Combinatorica`, and a fast approximation to the diameter by PseudoDiameter[g] in the Mathematica package GraphUtilities` . Precomputed diameters for many named graphs can be obtained using GraphData[graph, "Diameter"].
