%N Numbers which are not divisible by any of their digits in at least one base.
%C It seems likely all integers greater than 120 appear in this sequence
%e 9 is excluded because it can be written as 111111111, 1001, 100, 21, 14, 13, 12, 11, 10 or 9 and in every case there is a digit which divides 9; 11 is in the sequence because in base 4 it is written 23 and 11 is not divisible by either 2 or 3
