%N A066853 Number of different remainders (or residues) for the Fibonacci numbers 
               (A000045) when divided by n (i.e. the size of the set of F(i) mod 
               n over all i).
%C A066853 The Fibonacci numbers mod n for any n are periodic - see A001175 for 
               period lengths. - Ron Knott (ron(AT)ronknott.com), Jan 05 2005
%e A066853 a(8)=6 since the Fibonacci numbers, 0,1,1,2,3,5,8,13,21,34,55,89,144,
               .. when divided by 8 have remainders 0,1,1,2,3,5,0,5,5,2,7,1 (repeatedly) 
               which only contains the remainders 0,1,2,3,5 and 7, i.e. 6 remainders, 
               so a(8)=6
%e A066853 a(11)=7 since Fibonacci numbers reduced modulo 11 are {0, 1, 2, 3, 5, 
               8, 10}.
