A hexaflake has 7n-1 hexagons in its nth iteration, each smaller by 1/3 than the hexagons in the previous iteration. Its exterior boundary is the von Koch flake, and the full boundary contains an infinite number of Koch snowflakes. The Hausdorff dimension of the hexaflake is equal to ln(7)/ln(3), approximately 1.7712. It may also be constructed by projecting the Cantor cube onto the plane orthogonal to its main diagonal.
A closely related fractal, the Sierpinski hexagon, is formed by repeatedly replacing each hexagon by six smaller hexagons, omitting the central seventh hexagon. It is named after the work of Wacław Sierpiński and by analogy to the Sierpinski triangle, and has the same Koch snowflake exterior boundary as the hexaflake.
