%N A089493 a(n) = smallest k such that the Reverse and Add! trajectory of A063048(n) 
               joins the trajectory of k.
%C A089493 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.
%C A089493 a(n) determines a 1-1-mapping from the terms of A063048 to the terms 
               of A070788. For the inverse mapping cf. A089494.

%e A089493 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.
%Y A089493 Cf. A063048, A070788, A089494.
