Let $G_{m,n,k} = mathbb{Z}_m ltimes_k mathbb{Z}_n$ be the split metacyclic group, where $k$ is a unit modulo $n$. We derive an upper bound for the diameter of $G_{m,n,k}$ using an arithmetic parameter called the textit{weight}, which depends on $n$, $k$, and the order of $k$. As an application, we show how this would determine a bound on the diameter of an arbitrary metacyclic group.
Let $m,n,r$ be positive integers, and let $G=langle arangle: langle brangle cong mathbb{Z}_n: mathbb{Z}_m$ be a split metacyclic group such that $b^{-1}ab=a^r$. We say that $G$ is {em absolutely split with respect to $langle arangle$} provided that f
Let $Gamma(G,S)$ denote the Cayley graph of a group $G$ with respect to a set $S subset G$. In this paper, we analyze the spectral properties of the Cayley graphs $mathcal{T}_{m,n,k} = Gamma(mathbb{Z}_m ltimes_k mathbb{Z}_n, {(pm 1,0),(0,pm 1)})$, wh
Let $text{Mod}(S_g)$ be the mapping class group of the closed orientable surface $S_g$ of genus $ggeq 2$. In this paper, we derive necessary and sufficient conditions under which two torsion elements in $text{Mod}(S_g)$ will have conjugates that gene
Let W be an arbitrary Coxeter group. If two elements have expressions that are cyclic shifts of each other (as words), then they are conjugate (as group elements) in W. We say that w is cyclically fully commutative (CFC) if every cyclic shift of any
We define an excedance number for the multi-colored permutation group, i.e. the wreath product of Z_{r_1} x ... x Z_{r_k} with S_n, and calculate its multi-distribution with some natural parameters. We also compute the multi-distribution of the par
