Comments

a(n) <= A063048(n); a(n) = A063048(n) iff the trajectory of A063048(n) does not join the trajectory of any smaller number, i.e. A063048(n) is also a term of A070788.

a(n) determines a 1-1-mapping from the terms of A063048 to the terms of A070788. For the inverse mapping cf. A089494.

Example

A063048(3) = 1997, the trajectory of 1997 joins the trajectory of 106 = A070788(8) at 97768, so a(3) = 106. A063048(7) = 10577, the trajectory of 10577 joins the trajectory of 1 = A070788(1) at 7309126, so a(7) = 1.
