English: Tetration by escape. This is a fractal of tetration showing the points in the complex plane that escape to infinity under iteration. This fractal is similar to the Mandelbrot fractal except it is an exponential map instead of a quadratic map. The fractal was created using Fractint and shows from -4.5 to 3.5 of the real axis and from –3i to 3i on the imaginary axis.
