COMMENTS
A positive integer k belongs to the sequence iff there exists a positive integer n so that each of the first k multiples of n contains the decimal digit 1, but (k+1)*n does not contain the decimal digit 1, and no smaller value of n has this property for the same value of k.
REFERENCES
3 is a term because the first three multiples of 51 (51, 102, 153) all contain the decimal digit 1, and this is the unique longest sequence of this kind whose first term is 51 or less.
