On Transiso Graph

Abstract

In this note, we define a new graph ${\Gamma }_d(G)$ on a finite group $G$, where $d$ is a divisor of $|G|$. The vertices of ${\Gamma }_d(G)$ are the subgroups of $G$ of order $d$ and two subgroups $H_1$ and $H_2$ of $G$ are said to be adjacent if there exists $S_i\in \mathcal{T}(G,H_i)$ $(i=1,2)$ such that $S_1\cong S_2$. We shall discuss the completeness of ${\Gamma }_d(G)$ for various groups like finite abelian groups, dihedral groups and some finite $p$-groups.
