Tetration Fractal

The colored areas of the escape fractals escape to infinity. The fractal you provided above is a period fractal, the inverse of the escape fractal. The red area converges, the yellow is period two, green period three. The colors follow the color spectrum.

Is there periods of any length? Like period 87,or bigger?
If so one of tge approaches possible will be to define a different formula for each property. 
Converge, diverge towards infinity (which I did) and nth periodic.

Check out the triangular area at the far left of the plot. All the periods are a minimum of period 24.
