Amazingly, this corresponds to one less than the number of disks to be moved at th step in the optimal solution to the
tower of Hanoi problem: 1, 2, 1, 3, 1, 2, 1, 4,
1, 2, 1, ... (OEIS A001511). The parity
of this sequence is given by 1, 0, 1, 1, 1, 0, 1, 0, 1, 0, 1, 1, ... (OEIS A035263)
which, amazingly, also corresponds to the accumulation
point of
cycles through successive bifurcations.
