This paper investigates α d , i ∈ {2,3,4}, selection principles (which are modification of known selection principles of Koy cinac) on a double sequence of double sequences of real numbers which converge to a point a ∈ R in Pringsheim's sense. A stronger result than one given in (6) will be proved for the α d selection principle. Also, two more propositions will be proved for the S d andS φ 1 selection principles, which are also improvements of results given in (6).
