A graph whose nodes are sequences of symbols from some alphabet and whose edges indicate the sequences which might overlap. The above figures show the first few -dimensional de Bruijn graphs on symbols for . The graph is implemented in the Wolfram Language as DeBruijnGraph[m, n].
The independence number of the de Bruijn graphs for , 2, ... are given by 1, 2, 3, 7, 13, 28, ... (OEIS A006946).
