Here are the pictures of the universal function at the superstable
These pictures hint at the fractal nature of the limiting
graph as
Comparing these pictures, we see at each period-doubling
the horizontal segments of the previous graph are replaced by
shrunken (sometimes vertically reflected) copies of the
(At the scale of our pictures, this is clearest comparing the
As additional evidence for the fractal character of this universal function, note the red part of the picture is a scaled (and reflected) version of the blue part.
