Technical data for this type of fractal : click here.

For the fractal here :
fn1=tan, fn2=ident, fn3=ident, fn4=ident
real(p1) = 3, imag(p1) = 4, real(p2) = 0, imag(p2) = 0, real(p3) = 0.093, imag(p3) = -0.08

Note : zoom on the center of the spiral of the previous fractal (C10-520).
This fractal requests a long calculation time (compared to all the previous fractals C10-xxx).
The next four fractals request also a long calculation time.
