Sierpiński gasket


Let S0 be a triangular area, and define Sn+1 to be obtained from Sn by replacing each triangular area in Sn with three similar and similarly oriented triangular areas each intersecting with each of the other two at exactly one vertex, each one half the linear scale of the original in size. The limiting set as n (alternately the intersectionMathworldPlanetmath of all these sets) is a Sierpiński gasket, also known as a Sierpiński triangleMathworldPlanetmath.
