The cocktail party graph of order n, also called the hyperoctahedral graph, n-octahedron graph O_n, n-dimensional octahedron , matching graph , or Roberts graph, is the graph consisting of two rows of paired nodes in which all nodes but the paired ones are connected with a graph edge. It is the graph complement (n P_2)^_ of the ladder rung graph n P_2 and the dual graph of the hypercube graph Q_n. It is also the skeleton of the n-cross polytope (which is the origin of its designation as a hyperoctahedral graph by some authors). It is the complete n-partite graph K_(2, ..., 2_︸_n) andis also variously denoted K_(n×2) (e.g., Brouwer et al. 1989, pp. 222-223) and K_(n(2)) (e.g., Stahl 1978; White 2001, p. 59). This graph arises in the handshake problem.
We guarantee you’ll find the right tutor, or we’ll cover the first hour of your lesson.
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!
