Maximum sum element orders of all proper subgroups of PGL(2, q)

author

Abstract:

In this paper we show that if q is a power of a prime p , then the projective special linear group PSL(2, q) and the stabilizer of a point of the projective line have maximum sum element orders among all proper subgroups of projective general linear group PGL(2, q) for q odd and even respectively

A new characterization of $L_2(q)$ by the largest element orders

‎We characterize the finite simple groups $L_2(q)$ by the group orders and the largest‎ ‎element orders‎, ‎where $q$ is a prime or $q=2^a$‎, ‎with $2^a+1$ or $2^a-1$ a prime‎.

Polytopes with groups of type PGL2(q)

There exists just one regular polytope of rank larger than 3 whose full automorphism group is a projective general linear group PGL2(q), for some prime-power q. This polytope is the 4-simplex and the corresponding group is PGL2(5) ∼= S5.

characterization of‎ ‎$a_5$ and $psl(2,7)$ by sum of element orders

let $g$ be a finite group‎. ‎we denote by $psi(g)$ the integer $sum_{gin g}o(g)$‎, ‎where $o(g)$ denotes the order of $g in g$‎. ‎here we show that‎ ‎$psi(a_5)< psi(g)$ for every non-simple group $g$ of order $60$‎, ‎where $a_5$ is the alternating group of degree $5$‎. ‎also we prove that $psi(psl(2,7))
