On the global breadth of finite groups with nontrivial partitions

Seid Kassaw Muhie, Daniele Ettore Otera, Francesco G. Russo

In a series of recent contributions on the notion of global breadth $B (G)$ of a finite group $G$ , it was interesting to observe the structural conditions arising from the…

Permutability degrees of finite groups

Daniele Ettore Otera, Francesco G. Russo

Given a finite group $G$ , we introduce the \textit{permutability degree} of $G$ , as $p d (G) = \frac{1}{∣ G ∣ ∣ L ( G ) ∣} X \in L (G) \sum ∣ P_{G} (X) ∣,$ where…

On minimal non- $C L$ -groups

Daniele Ettore Otera, Francesco G. Russo

If $m$ is a positive integer or infinity, the $m$ -layer (or briefly, the layer) of a group $G$ is the subgroup $G_{m}$ generated by all elements of $G$ of order $m$ . This notion goes…

Subgroup S-commutativity degrees of finite groups

Daniele Ettore Otera, Francesco G. Russo

The so--called subgroup commutativity degree $s d (G)$ of a finite group $G$ is the number of permuting subgroups $(H, K) \in L (G) \times L (G)$ , where $\mathrm{L}(G)…
