COMMENTS

If m is a term, 10*m is also a term; so, terms with no trailing zeros are all primitive terms.

Index entries for sequences related to decimal expansion of 1/n.

EXAMPLE

m = 6 is a term since 1/6 = 0.16666666666...

m = 13 is a term since 1/13 = 0.076923076923...

m = 103125 is a term since 1/103125 = 0.00000969696...
