Suppose H \le K \le G. We say that H if weak normal subset-conjugacy-determined in K relative to G if, for any normal subsets A,B \subseteq H such that there exists g \in G with gAg^{-1} = B, there exists k \in K such that kAk^{-1} = B.

The modifier weak here denotes that g and k may not have the same element-wise action on A.
