I agree - the two sequences coincide.

• The worst case scenario is that the original number sequence came from someone s high school homework assignment. :) Well, yes the level is not a high level.

"The worst case scenario is that the original number sequence came from someone's high school homework assignment. :)"

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.
