%N Number of odd cycles in range [A014137(n-1)..A014138(n-1)] of permutation A057505/A057506, with fixed-points of both A057163 and A057164.
%C See comment at A080973. Because A057163 can fix only binary trees of odd size, the even-indexed terms are all 0 after n>0.
%F a(n) = A081148(n)-A081153(n).
%Y Bisection: A081156.
%Y Cf. A081148, A081153.
%Y Cf. A014137, A014138, A057505, A057506, A057163, A057164.
