Every graph may be defined by at least one sentence; for instance, one can define any -vertex graph by a sentence with + variables, one for each vertex of the graph, and one more to state the condition that there is no vertex other than the vertices of the graph. Additional clauses of the sentence can be used to ensure that no two vertex ...
