1. On each legal circle the centers of six legal circles with the same radius can be found.
2. If the radius of the initial circle is defined as 1, the radius of any legal circle can be written as 2-n, and any arc width can be written as 2-m, where n, m are non-negative integers.
3. On a given area, there are about four times as many circles with radius 2-n-1, as there are circles with radius 2-n.
4. Low-complexity art is in no way limited to Rules 1-6. For instance, a drawing that only partly obeys Rules 1-6 may be a work of low-complexity art, as long as the deviations can be uniquely determined by a short algorithm.
