The smallest number of vertices required to achieve this is called a ramsey number. The regions were connected with seven bridges as shown in figure 1a. Graphs can be represented by diagrams in which the elements are shown as points and the binary relation as lines joining pairs of points. Really too basic to be of any use save as a highlevel survey. Such graphs are called trees, generalizing the idea of a family. These four regions were linked by seven bridges as shown in the diagram.
