Given an ##nxm## array of evenly spaced points, what is the minimum number of straight lines to connect them in a closed loop? Here are the rules, start on one point and end on the same point. You cannot go through the same point more than once but can cross lines. For example, for a 2x2 array with four points, one can do it in three lines I believe. Thanks.
