connected graph

(mathematics)
A graph such that there is a path between any pair of nodes (via zero or more other nodes).

Thus if we start from any node and visit all nodes connected to it by a single edge, then all nodes connected to any of them, and so on, then we will eventually have visited every node in the connected graph.

We therefore adopt and extend the approach employed by Mike Keith to study the related problems of king-and queen-graphable words [2], Specifically, we define an alphabet A as a set of letters, and a word graph for a word with 1 [less than or equal to] n [less than or equal to] [absolute value of A] distinct letters as the connected graph of order n that has an edge (a<sub>1</sub>, a<sub>2</sub>) if the letters a<sub>1</sub>, a<sub>2</sub> [member of] A are adjacent to each other in the word, irrespective of order.
