In chess. A “knight’s move” consists of two squares either vertically or horizontally and then one square is a perpendicular direction. Depending on where the knight is situated, he has a minimum mobility of two moves—when in a corner—and a maximum mobility of eight moves. Let C be a graph with v=64, its vertices corresponding to the squares of a chessboard. Let two vertices of C be joined by an edge whenever a knight can go from one of the corresponding squares to the other in one move. Does C have an Euler Walk? Explain, but you do not have to draw C to answer.
