| The next period-10 orbit (which finishes the sequence) is the period doubling of the period-5 orbit. The limit point -2 +6π 2 / 46 = -1.98554 lies within the period-5 M-set. |
A lot of these fine structures are visible better in the quartic Mandelbrot
set antenna below. They have the same topology as the quadratic map filaments
but differ in metric behaviour.
