Technical data for this type of fractal : click here (C07-010).

For the fractal here :
fn1() = ident(), fn2() = recip(), fn3() = cotanh(), fn4() = sinh().
real(p1) = 2, imag(p1) = 4, real(p2) = 8, imag(p2) = 2, real(p3) = 1, imag(p3) = 1

If imag(p1) = 2 instead of 4, the shape of the fractal, with a different palette of colors, is the following :
