Web(0; 1;0) with values f(x;y;z) = 5 and 1. Case 2: If z ̸= 0, the third equation gives = 1. Then the second equation gives 2y = 2y or y = 4. Then plugging x = 2 into x y = 1 gives 2 + 4 = 1 or = 4 3. This gives x = 2 3, y = 1 3. But this value of y is inconsistent with y2 z2 = 1, so we have no additional points to consider.
