Then you also have 4 lines from the second point to each of the others, but you have already accounted for one of those 4 lines in the 4 lines from the first point, so you can only create 3 new ones.  Similarly, from the 3rd point you can only create 2 new lines, and from the 4th point, only 1 new line.  Finally, when you get to the 5th point, all possible lines have been created, and you can create no new lines.\r<BR>\n" );
