The power graph $G = P(Ω)$ of a finite group $Ω$ is a graph with the vertex set $Ω$ and two vertices $u, v \in Ω$ form an edge if and only if one is an integral power of the other. Let $D(G)$, $A(G)$, $RT(G)$, and $RD(G)$ denote the degree diagonal matrix, adjacency matrix, the diagonal matrix of the vertex reciprocal transmission, and Harary matrix of the power graph $G$ respectively. Then the $A_α$ and $RD_α$ matrices of $G$ are defined as $A_α(G) = αD(G) + (1-α)A(G)$ and $RD_α(G) = αRT(G) + (1-α)RD(G)$. In this article, we determine the eigenvalues of $A_α$ and $RD_α$ matrices of the power graph of group $ \mathcal{G} = \langle s,r \, : r^{2^kp} = s^2 = e,~ srs^{-1} = r^{2^{k-1}p-1}\rangle$. In addition, we calculate its distant and detotar distance degree sequences, metric dimension, and strong metric dimension.
