Technical data for this type of fractal : click here (C06-010).

For the fractal here :
fn1() = tanh(), fn2 = ident(), fn3 = ident(), fn4 = zero().
real(p1) = 1, imag(p1) = 128, real(p2) = 1, imag(p2) = 1, real(p3) = 0, imag(p3) = 4

The parameters of this fractal and of the two three fractals C06-10 / C06-20 / C06-30 are identical,
but another area of the fractal is selected. The two fractals C06-30 / C06-40 have the same palette of colors.
