Mandelbrot Set Lemniscate
A curve on which points of a map 
(such as the
Mandelbrot set) diverge to a given value 
at the same
rate. A common method of obtaining lemniscates is to define an integer
called the count which is the largest 
such that 
where 
is usually taken
as 
. Successive counts
then define a series of lemniscates, which are called equipotential
curves by Peitgen and Saupe (1988).
