%N Beginning with 1 distinct numbers. A new digit say n occurs after exhausting all possible numbers containing up to and at most n-1 digits, in increasing order (in a typical manner explained in the example) formed by already occurring digits.
%C The sequence is not base dependent. Subsidiary sequences: (1) Indices of the digit n. (2) Indices of r occurrences of 1. (3) Indices of r occurrences of any digit k.
%e After 3 all numbers using 1 and 3 are placed in increasing order with digit multiplicity. Then all numbers using 2 and 3 are placed in increasing order then all numbers using 1,2,3 are placed in the same fashion. And the next term is 4.
%Y Cf. A000110, A096108.
