Let L denote the set of all points of the plane with integer coordinates

every positive integer n, we have T(x(n)) = x(n-1).
It seems that you are asking for those elements x in P such that T(x)
= x. These are usually called "stable configurations".
No he isn't. He's asking for configurations that have a possible
ancestry of infinite length.
Perhaps "ageless" is a better term than "timeless".
