Threefold is the result of another stab at generating a three-arbitrary-quadratic-Julias system. Whereas with Triple Matchmaker I modified Matchmaker to add more parameters, with Threefold I modified Twofold, the system from which I derived Matchmaker.

Matchmaker is \frac{z + a}{b(z^2 + 1)} and twofold is \frac{z}{b(z^2 + 1)}. Threefold is \frac{z}{b(z^3 + 2)} and has the same basic structure as Twofold, except that instead of orbits having a twofold symmetry to their fates, they have a threefold symmetry.

This is a dusty Julia from a point outside the unit disk in the parameter space; this outer region, as in Twofold, has only an attracting fixed point at zero.
