A character theoretic formula for base size II

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. The base size o…

On Cameron's Greedy Conjecture

Coen del Valle, Colva M. Roney-Dougal

A base for a permutation group $G$ acting on a set $Ω$ is a subset $B$ of $Ω$ whose pointwise stabiliser $G_{(B)}$ is trivial. There is a natural greedy algorit…
