As an undergraduate student at Metropolitan State University of Denver, Bryan Curtis worked closely with his adviser Dr. Diane Davis. Under her guidance, Bryan completed many independent studies.  One such study resulted in a talk at the 2015 Join Mathematics Meetings and eventually, this paper.  Bryan is now pursuing his PhD in mathematics at the University of Wyoming.  If you have any questions or comments about this paper, please feel free to contact Bryan.
