And I admit that the quadratic is a simpler description,

but since I had my ggf() at hand, I found the other before.

Maximilian - The values you give seem to be correct, but the polynomials wrong:

? for(x=2,20, print(f(x)))

Well, yes the level is not a high level. What i mean is the polinomial fits pretty well, but originally i was thinking

in a base b and numbers b^2+(b-2^2)^2+(b-3^2)^2. Nothing very hard, but for b=10 you get 10^2+6^2+1^2=137,

which obsesses so much David. It was just fun for me.
