a(n) is the cycle length of the first differences of numbers k satisfying
Fib(k) mod n = k mod n
Example with n=3:
Fib(k) mod 3:
k mod 3:
accepted k values indicated by x:
accepted k values:
first differences of k values:
after this the cycle repeats, so a(3)=8.
Beginning of the sequence:
a(n)=3,8,3,8,6,16,3,8,14,10,4,28,24,16,3,36,6,18,11,16,15,48,3 for n=2..24
It is not in OEIS, should it be?
