Abstract. We attempt a slingshot model interpretation of the unusual association of some 1 and 1/3 dozen nonstellar galaxian objects around the parent optical galaxy of the giant radio galaxy DA 240 (also known as 0748.6+55.8 (J2000)). Similar interpretation may be possible for another large radio galaxy 3C 31 (also known as NGC 383; 0104.6+32.1 (1950.0).
