fractals and mobius strip

 Sierpinski

The Sierpinski triangle is a fractal created by repeatedly removing smaller equilateral triangles from a larger one. It's a self-similar shape, meaning each smaller triangle within the structure is identical in shape to the entire figure. This fractal is named after the Polish mathematician Wacław Sierpiński.
