ABSTRACT
Solution It is easy to write down many solutions (x, y, z, w, t) of this equation, for example, (1,2,2,7,2) or (2,0,6,5,1) or ( 2,6,5,0,1) or (0,3,0,3,8). With each of these solutions we can associate a diagram of dots (•) and lines ( | ) , as follows:
With (1,2,2,7,2) associate the diagram • | • • | • • | • • • • • • • | • • .
