Irredundant bases for soluble groups

Sofia Brenner, Coen del Valle, Colva M. Roney-Dougal

Let $Δ$ be a finite set and $G$ be a subgroup of $Sym (Δ)$ . An irredundant base for $G$ is a sequence of points of $Δ$ yielding a strictly descending chain of pointwi…

Greedy base sizes for sporadic simple groups

Coen del Valle

A base for a permutation group $G$ acting on a set $Ω$ is a sequence $B$ of points of $Ω$ such that the pointwise stabiliser $G_{B}$ is trivial. Denote the mini…
