It is afterall a fractal, and therefore only approximated at the horrendous resolution afforded by the dimensions selected. Whilte {NULE} gave a sepecific output to match, "gives a decent presentation of the Mandelbrot fractal" was also said which I believe warrants some artistic license.

UPDATE: I did a little comparison between 165213 and the original output; after alignment, cropping and overlaying. The results are below. There are definitely differences; 88+33 out of 2440 to be exact
