2) Investigate the maximum Node Total that can be made with any number of matches.
3) Now investigate patterns of matches with no loose ends ( no 1 nodes) For example 3 matches can be arranged in just one way with a Node Total of 6.

How many different node totals are possible with 4 matches?
With 5 matches?
