The (m, n)-de Bruijn graph is a non-simple regular directed graph whose nodes are sequences of n copies of m symbols from some alphabet and whose edges consist of pairs of vertices such that shifting the symbols of the first vertex by one place to the left and adding any symbol at the end corresponds to the symbol of the second vertex. For example, the (3, 2)-de Bruijn graph is illustrated above. The above figures show the first few n-dimensional de Bruijn graphs on n copies of m symbols for m, n>=2. The (m, n)-de Bruijn graph is implemented in the Wolfram Language as DeBruijnGraph[m, n].

Club Z! has connected me with a tutor through their online platform! This was exactly the one-on-one attention I needed for my math exam. I was very pleased with the sessions and ClubZ’s online tutoring interface.
My son was suffering from low confidence in his educational abilities. I was in need of help and quick. Club Z! assigned Charlotte (our tutor) and we love her! My son’s grades went from D’s to A’s and B’s.
I’ve been using Club Z’s online classrooms to receive some help and tutoring for 2 of my college classes. I must say that I am very impressed by the functionality and ease of use of their online App. Working online with my tutor has been a piece of cake. Thanks Z.
Jonathan is doing really well in all of his classes this semester, 5 A’s & 2 B’s (he has a computer essentials class instead of PLC). In his Algebra class that Nathan is helping him with he has an A+.
Sarah is very positive, enthusiastic and encourages my daughter to do better each time she comes. My daughter’s grade has improved, we are very grateful for Sarah and that she is tutoring our daughter. Way to go ClubZ!
