It can be generated from using this algorithm:
- Image 1:
- Start with a square.
- Subtract a square half the original length and width (one-quarter the area) from the center.
- Image 2:
- Start with the previous image.
- Scale down a copy to one-half the original length and width.
- From each of the quadrants of Image 1, subtract the copy of the image.
- Images 3–6:
- Repeat step 2.
T-square has a fractal dimension of ln(4)/ln(2) = 2. The black surface extent is almost everywhere in the bigger square, for, once a point has been darkened, it remains black for every other iteration ; however some points remain white.
The fractal dimension of the boundary equals .
