%N The average cycle length of cycles in Fibonaccilike sequences modulo n over all starting pairs of remainders.
%C a(n) = Round(A233246(n)/n^2.
%C If n is in A064414, then a(n) is the average distance between two neighboring multiples of n.
%C If n is in A064414, then a(n)/2 is the average distance to the next zero over all starting pairs of remainders.

%e For n=4 there are four possible cycles: A trivial cycle of length 1: 0; two cycles of length 6: 0,1,1,2,3,1; and a cycle of length 3: 0,2,2. Hence, a(4)=Round((1+9+36+36)/16)=5.
