We introduce and characterize the notion of $\mathbb R$-factorizability of $G$-spaces in the category G-Tych. For $G$-spaces with $d$-openly acting groups, we establish the equivalence of $\mathbb R$-factorizability and$\mathbb R$-factorizability in G-Tych. We prove the$\mathbb R$-factorizability in G-Tych of every$\mathbb R$-factorizable $G$-space with transitive action whose phase spacepossesses the Baire property. The Dieudonne completion of an$\mathbb R$-factorizable group is shown to be the phase spaceof a $G$-space $\mathbb R$-factorizable in G-Tych. We characterize$\mathbb R$-factorizability in G-Tych under passageto the $G$-compactification.
