%N Sum of the number of repeating digits for each reciprocal of integer m, where n>m>1 and n is the base.
%C No digits are counted as repeating for 1/m if 1/m terminates.
%C Equivalent to n>=m>=1, since 1/n and 1/1 do not have repeating digits in any integer base n.
%e 7th term considers octal: the fractions 1/2, 1/3, 1/4, 1/5, 1/6 and 1/7 have 0, 2, 0, 4, 2 and 1 repeating (octal) digits respectively, for a total of 9.
%e 9th term considers decimal: the fractions 1/2, 1/3, 1/4, 1/5, 1/6, 1/7, 1/8 and 1/9 have 0, 1, 0, 0, 1, 6, 0 and 1 repeating (decimal) digits respectively, for a total of 9.
