The research in this article continues the investigation of the cardinal functions F-theta and t(theta) for absolutes of Hausdorff spaces. The relationship among the cardinal functions t, t(theta), F and F-theta are obtained for both of the Iliadis and Banaschewski absolutes for some well-known spaces.
