## Definition

Suppose is a finite group and is a prime number. Suppose, further, that is a conjugacy functor on . We say that **controls strong fusion** on if, for any -Sylow subgroup of , is a subset-conjugacy-determined subgroup inside . In other words, given two subsets and in that are conjugate by , there exists such that conjugation by has the same effect as conjugation by on every element of .
