Just wondering:
If we iterate the function a(n) = n - A002828(n) (
https://oeis.org/A002828) from any starting value k, will the
trajectory visit every square-1
(A005563) < k before it reaches zero?
Which would imply that there would be only one infinite sequence a_n such
that a(n-1) = a(n) - the least number of squares that add up to a(n).
Then, would there be any regularity in the derived sequence counting the
number of iterations needed to hop from A005563(n+1) to A005563(n) ?
Cheers,
Antti
