Why i can get only 2^9 number, a marker is composed by 36 "square"  than a can create 2^36.

The max numer is 512 = 2^9 why ?

You'll need to use multiple markers if you want to increase the number range.

The ID is encoded multiple times - on each edge of the frame - using a different base pattern of dark and light blocks. This redundancy makes the marker more robust for detection and tracking. Take a look at the PDF included with the FrameMarkers sample and you can see how the marker ID's are incremented from 0 to 3.
