Dragon Curve - Terdragon

The terdragon can be written as a Lindenmayer system:

  • angle 120°
  • initial string F
  • string rewriting rules
    • F ↦ F+F−F.

It is the limit set of the following iterated function system:

\mbox{where }\lambda=\frac{1}{2}-\frac{i}{2\sqrt{3}} \text{ and }\lambda^*=\frac{1}{2}+\frac{i}{2\sqrt{3}}.
