A n-crossed prism graph for positive even n (a term introduced here for the first time), is a graph obtained by taking two disjoint cycle graphs C_n and adding edges (v_k, v_(2k + 1)) and (v_(k + 1), v_(2k)) for k = 1, 3, ..., (n - 1). The crossed prism graphs are cubic vertex-transitive (and hence appear in Read and Wilson 1998, though without any designation indicating membership in a special graph family), weakly regular, Hamiltonian, and Hamilton-laceable. The 2n-crossed prism graphs are toroidal for n>2 (E. Weisstein, May 9, 2023). Simmons used the term "polygonal bigraph on 4m vertices" for graphs isomorphic to the m-crossed prism graph and investigated the Hamilton-laceability and structure of Hamiltonian paths in these graphs.
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!
