%N Triangle array: row n lists the number of repeating digits of 1/2 through 1/(n-1) in base n, or 0 if it terminates.

%e Rows show the number of repeating digits for:

%e 1/2 base 3

%e 1/2 base 4, 1/3 base 4

%e 1/2 base 5, 1/3 base 5, 1/4 base 5

%Y Cf. A066799 (similar table but does not differentiate terminating versus non-terminating values.)

%K nonn,tabl,base

%O 3,5
