%N List the positions of all digits 0 in the concatenation of all terms, not necessarily in order. This is the lexicographically earliest such sequence.
%C See A210415 for comments, links, and code.

%e The sequence cannot start with 0 (offset starting from 1), 1 (in first position we have 1 not 0) or 2 (the second entry cannot start with 0). Then 3. Then 10 that is the minimum number with 0 as second digit. And so on.
%Y Cf. A210415-A210423. See A167519 for another version.
