%N A107411 Each digit of a(n) appears in a(n+1) and a(n+1) > a(n) is minimal.
%C A107411 Starting with another integer as 0 (the "seed") would lead to another 
               sequence.
%e A107411 After 100 we get 101 (and not 1000) because the lone 0 in "101" is considered 
               as the copy of both zeros of "100".
