Abstract: We will discuss the problem of whether any „big” set on the plane contains a product of a „big” set and a perfect set. The main motivation is the old result of Eggleston saying that each measurable set on the plane having positive measure contains a product of measurable set of positive measure and perfect set. The results were obtained together with R. Rałowski and M. Michalski.
