%N Record values in A039932.
%C The positive integer n belongs to the sequence iff there exists a positive integer k so that each of the first k multiples of n contains the decimal digit 1, but no smaller n has this property for the same value of k.
%e 51 is a term because the first three multiples of 51 (51, 102, 153) all contain the digit 1, and 51 is the least positive integer with this property.
%Y Cf. A319548, A039932, A317173. Subset of A011531.
