%N Lexicographically earliest sequence starting with a(1) = 23 with no duplicate terms such that the n-th digit of the sequence is not a divisor of a(n).
%C This sequence doesn't include any term containing at least one digit 0 or one digit 1 as we want the sequence to extend forever.
%C Any a(1) < 23 would be in contradiction with the definition.

%e The sequence starts with 23,2,3,4,5,6,7,8,9,22,25,27,29,24...
%e The 1st digit of the sequence is 2 and 2 is not a divisor of a(1) = 23;

%e the 3rd digit of the sequence is 2 and 2 is not a divisor of a(3) = 3;
