Simplicial complexes defined on groups

open access: yesOpen Mathematics
This study makes some preliminary observations towards an extension of current work on graphs defined on groups to simplicial complexes. I define a variety of simplicial complexes on a group, which are preserved by automorphisms of the group, and in many

Existence and Classification of 3‐Regular Symmetric Graphs of Order 6pq With Distinct Primes p and q

open access: yesJournal of Mathematics, Volume 2025, Issue 1, 2025.
A graph Σ is said symmetric if its automorphism group acts transitively on the set of its arc. Let p < q be two distinct prime integers. This paper demonstrates that connected 3‐regular symmetric graphs of order 6pq exist if and only if the pair (p, q) belongs to the set (5, 19), (19, 37), (37, 73), which up to isomorphism there are nine sporadic ones,

Certain Structural Properties for the Direct Product of Cayley Graphs and Their Theoretical Applications

open access: yesJournal of Mathematics, Volume 2024, Issue 1, 2024.
Symmetry properties are of vital importance for graphs. The famous Cayley graph is a good mathematical model as its high symmetry. The normality of the graph can well reflect the symmetry of the graph. In this paper, we characterize the normality of the direct product of Cayley graphs and give a sufficient and necessary condition for the direct product
