Irredundant bases for finite groups of Lie type

Nick Gill and Martin W. Liebeck

Vol. 322 (2023), No. 2, 281–300
Abstract

We prove that the maximum length of an irredundant base for a primitive action of a finite simple group of Lie type is bounded above by a function which is a polynomial in the rank of the group. We give examples to show that this type of upper bound is best possible.
