 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.   https://magazine.thingimajigs.com/wp-content/uploads/2016/02/Sierpinski-Zoom-01.gif
