On the porosity of Baire class functions

We consider the strong porosity of the family of quasicontinuous and cliquish functions in the space of Baire class functions. We show that the family of Baire functions in $${\mathcal{B}}_{\alpha }$$ -class is strong porous in the family of $${\mathcal{B}}_{\beta }$$ -class for α < β < ω1.
