%N A091201 Number of orbits of length n under the map whose periodic points are counted by A061688.
%C A091201 Old name was: A061688 appears to count the periodic points for a certain map. If so, then this is the sequence of the numbers of orbits of length n under that map.

%F A091201 If b(n) is the (n+1)th term of A061688, then a(n) = (1/n)*Sum_{d|n}mu(d)b(n/d).
%e A091201 b(1)=1,b(3)=48844, so a(3)=(1/3)(48844-1)=16281.
