The period doubling region in the logistic map has specific cycle orders within each branching region.
The cycle order in each region remains constant and follows a specific pattern, such as [0, 2, 1, 3] for one of the regions.
The cycle orders for subsequent regions follow a similar pattern of increasing numbers, such as [0, 4, 6, 2, 1, 5, 3, 7] and [0, 8, 12, 4, 6, 14, 10, 2, 1, 9, 13, 5, 3, 11, 7, 15].
There is ongoing exploration into whether the cycle order remains constant within a region of constant period and what general conclusions can be drawn from these patterns.
