Cross Menger (Jerusalem) Fractal
Many classical fractal figures, such as the Sierpinski carpet, Sierpinski sieve, Menger sponge and tetrix are created by starting with a simple shape (a square, triangle, cube or tetrahedron) and then repeatedly assembling scaled versions of the shape.[more]
The cross Menger (or Jerusalem) fractal follows a similar procedure. However, where other fractals commonly use a simple rational scaling factor (commonly or ), this uses a scaling factor of .[less]
