*Definition [#wd0270e0]
-A topological space (X,τ) is said to be T_{FF} if for any two disjoint, finite sets F_1 and F_2 either F_1 is [[weakly separated]] from F_2 of F_2 is weakly separated form F_1
*Property [#ne744f74]
-T_{FF} implies T_Y.
-A topological space (X,τ) is a T_{FF} space if and only if either
