Abstract

We say that a finite group GG acting on a set Ω\Omega has Property ()p(*)_p for a prime pp if PωP_\omega is a Sylow pp-subgroup of GωG_\omega for all ωΩ\omega\in\Omega and Sylow pp-subgroups PP of GG. Property ()p(*)_p arose in the recent work of Tornier (2018) on local Sylow pp-subgroups of Burger-Mozes groups, and he determined the values of pp for which the alternating group AnA_n and symmetric group SnS_n acting on nn points has Property ()p(*)_p. In this paper, we extend this result to finite 22-transitive groups and we give a structural characterisation result for the finite primitive groups that satisfy Property ()p(*)_p for an allowable prime pp.
