This simple formula results in a quadruple bead. I have tried to make a simpler formula,
but the formula's fractal set is very sensitive to even small changes of the formula.


In the table below are scaling variants of this formula.
Explanation: scaling is: scaleFactor*f(z) + c

The start value is s = 1.0.

without scaling a quadruple bead
1.0 without scaling and mathematical rendering
0.9 close-by there are still beads,
but with a different surrounding
0.1 quadruple novas
-0.65 fourfold symmetry
