Technical data for this type of fractal : click here.

For the factal here :
fn1 = conj(), fn2 = tanh(), fn3 = tanh(), fn4 = cosh()
real(p1) = 4, imag(p1) = 4, real(p2) = 1, imag(p2) = 1, real(p3) = 16, imag(p3) = 1

Note.
The same parameters are used for this fractal and the previous one (see JMC-A99-072),
but here a simple change of the palette of colors generates a drastic change of the aspect of the fracttal.
Compare below the thumbnais of the two fractals.
