Robert P. Munafo, 2008 Feb 1.
The "nucleus" at the center of a 2-fold embedded Julia set. It consists of two rotated, distorted images of the 2-fold embedded Julia set, an example of bifurcation.
Here are a couple examples:

-1.748 305 132 642 920 80 +0.000 000 000 000 000 01i @ 3.7e-1

-1.748764596 +0.000000002i @ +0.000001450

-0.744539860355908380 +0.121723773894424824 i @ 6.0e-15
