1.1                                                         ARITHMAGONS










                  As  we have already learnt in  the  previous class, how  to calculate the  triangular
                  arithmagon.




                    Arithmagons are polygons with a circle number at each vertex and
                    a box number on each side, with each box number equal to the
                    sum of the two circle numbers next to it.


                                                              4
