Periodic strips

The width of the strip chosen for the first level de Bruijn diagram varies from 1 to 6 according to the options A to F. Wider strips are not available simply because of memory limitations, but execution time would also be a consideration if the strips were much wider.

The strip option calculates the second level de Bruijn diagram, which describes the sequencing of the partial strips (actually, it has been edited so that only loops remain). The number of nodes can be very large - up to for a strip of width w - , so the final display is adjusted accordingly. If , the connectivity matrix is displayed using 2x2 pixels on a green background.

Otherwise, if , the connectivity matrix is displayed with 1x1 pixels. If there are still more nodes, no matrix at all is shown.

In every case, it is possible to obtain a listing of the matrix elements of the second level matrix.
