A179193 Sum of the number of repeating digits for each reciprocal of integer m, where n>m>1 and n is the base. 0
0, 1, 1, 4, 1, 8, 9, 9, 9, 20, 15, 30, 22, 28, 23, 52, 33, 63, 58, 44, 65, 86, 84, 67, 68, 102, 135, 140, 80, 142, 171, 159, 142, 124, 88, 220, 204, 206, 224 (list; graph; refs; listen; history; text; internal format)

2,4

COMMENTS

No digits are counted as repeating for 1/m if 1/m terminates.

Equivalent to n>=m>=1, since 1/n and 1/1 do not have repeating digits in any integer base n.

EXAMPLE

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.

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.
