%N A079002 Numbers n such that the Fibonacci residues F(k) mod n form the complete
set (0,1,2,....,n-1).

second edition, Addison Wesley, ex. 6.85, p. 318, p. 562
%F A079002 Consists of the integers of the form: 5^k, 2*5^k, 4*5^k, 3^j*5^k, 6*5^k,
7*5^k and 14*5^k [see Concrete Mathematics]
%e A079002 Fibonacci numbers (A000045) are 0,1,1,2,3,5,8,.. and mod 5 these are
0,1,1,2,3,0,3,3,4,... i.e. all possible remainders mod 5 occur in
the Fib series mod 5, so 5 is in the series. This is not true for
n=8 so 8 is not in the series.
