Technical data for this type of fractal : click here (C01-01).

Here :
fn1() = ident(), fn2() = ident(), fn3 = ident(), fn4 = tanh()
real(p1) = 1, imag(p1) = 6, real(p2) = -3, imag(
p2) = 0, real(p3) = 0, imag(p3) = 0

With a zoom on an area on the top of the above fractal and with a different palette of colors the shape of the fractal looks like this :



With a zoom on another area of the above fractal, the result looks like this :
