%N A060370 Ratios (p-1)/d, where p is a prime and d is the number of digits of the
periodic part of the decimal expansion of 1/p.
%C A060370 The sequence of 2nd, 4th and following terms coincides with A006556,
which gives the "number of different cycles of digits in the decimal
expansions of 1/p, 2/p, ..., (p-1)/p where p = n-th prime different
from 2 or 5".
%F A060370 a(n) = (b(n)-1)/c(n), where b(n) and c(n) are the n-th terms of A000040
and A048595 respectively.
%e A060370 a(13) = 40/5 = 8, since 41 is the 13th prime and the periodic part of
1/41 = 0,02439024390... consists of 5 digits.
