Up with an even 24 points but only with the horizontal and vertical lines connect the far right of the second line of the circle office can not be used to connect lines as shown: Ideas: The recursive implementation, design a recursive function tf () to find the next node and connect to the first line of the first column of the point (1,1) as the second line of the first (2,1) coordinates of each point to compiling, tf function in the first look at their adjacent nodes The connection point and can then connect, then this node can be used to find the next node until the tf () function returns 0, on the return.
