The Replacement Property of PSL$(2,p)$ and PSL$(2,p^2)$

Abstract

In 2014, Benjamin Nachman showed that when pp\equiv1 mod 8, the 2-dimensional projective linear group over the field of pp elements fails the replacement property if the maximal length mm of an irredundant generating sequence for the group is 3. In addition, if m=4m=4, the group satisfies the property for any prime pp. In this paper, we will extend such classification for PSL(2,q)(2,q) where qq is pp and p2p^2 with conditions of modulo 8 and 10 on pp.
