Abstract

In infinite topological Fort space XX, for nonempty subsets C,DC,D of XX in the following text we answer to this question "Is there any λ\lambda and Top--design C(X,D,λ)C-(X,D,\lambda) of type ii?" for i=1,2,3,4i=1,2,3,4. We prove there exist λ\lambda and C(X,D,λ)C-(X,D,\lambda), Top--design of type 2 (resp. type 4) if and only if CC can be embedded into DD.
