Hm, I think we could create an array of coefficients with a first initial guess.

If we use Ansus' formula for the derivative we dont need to take the exponential.

Hence we dont need to switch between phase and function space and.

We can work all the time with the coefficient array.

The algorithm would then be:

Take some initial guess for .

Then compute the continuum sum.

Multiplying with .

add g'(0)/g(0)

Then take the integral.

Repeat these steps till convergent.

But my fear is that it will not converge.

Hey actually I never considered graph of tetration with complex bases. I would guess that it is somewhat distorted real tetration. But I think one would need contour plots, or complex color plots, to have a bigger picture.
