It should not die out. I am off to Bethlehem for Thanksgiving, so I will work on this upon my return. Bob.

David or Bob, What about this version of the sequence?
a(1) = 1, a(n) = smallest number NOT YET IN THE SEQUENCE such that the concatenation of a(n-1) and a(n) is a square.

It starts rather like A082209, 1, 6, 4, 9, 61, 504, 100, ... but it isn't in the OEIS. Oh, maybe it dies - could you check?
