%N A065374 Smallest k such that f(f(...f(k))) > 1, where f(k) = A065371(k) is iterated 
               n times.
%e A065374 a(2) = 13 because A065372(13) = 3 and A065372(i) = 1 for i < 13.
%e A065374 After 10 iterations of A065371 we have a sequence starting with 14896 
               1's followed by 6, so a(10)= 14897.
