1/7 = .142857... (repeated)
2/7 = .285714...
3/7 = .428571...
4/7 = .571428...
5/7 = .714285...
6/7 = .857142...
So, you get all n/7 from the same 'cycle' of 6 digits.
Let's call 7 a 'cyclic' integer.
The next cyclic integers are
17, 19, 23,...
They are all prime. But 11, 13, or 37 are NOT cyclic.
Anybody know a rule do determine if a prime is 'cyclic' or not?
