A C𝜃𝜃-group is a finite
group of order divisible by 3 in which centralisers of 3-elements are 3-groups. Several
authors have studied such groups; in particular it is known that, given the additional
hypothesis that the Sylow 3-subgroups intersect trivially, a simple C𝜃𝜃-group has
abelian Sylow 3-subgroups. In this note it is proved that this additional hypothesis is
superfluous.
