Mike,

...this image has a very prominent 6 way symmetry... [which] ...eventually breaks down and returns to 3 way...

There are some blue 3-sided figures in each of the 6 blue "arms" of the large 6-sided snow crystal-like figure, too. There are also 6 small, dark "heads" between each of the 6 blue "arms" that look a bit like the head of the figure in the painting "The Scream". A very nice winter fractal... What does the parent fractal look like? <---<< - Hal Lane ######################## # hallane@earthlink.net ######################## ---------------------------------------------------- Author: Mike Frazier Date: 2014-02-19 18:16 -500 To: Fractint and General Fractals Discussion Subject: [Fractint] Post 20140219 This fractal is a parallel resistor formula of the following equation: z = 1 / (1 / (z * (cos(z) - 1) - pixel) + 1 / (z ^ 3 + pixel)) The dominant z term is z^3 so it should have 3 way symmetry but this image has a very prominent 6 way symmetry. I zoomed into the center and the 6 way symmetry eventually breaks down and returns to 3 way and ends in a normal z^3 minibrot. The fractal is a deep zoom at a magnification of about 1e21 so I won't post the PAR file.
