In this study, we introduce the generalised double Hahn sequence space H?d as an extension of generalised Hahn sequence space hd defined by Goes [J. Math. Anal. Appl. 39 (1972), 477–494]. We give some topological properties of this space. Then, we characterize the classes(H?d:W) of four dimensional infinite matrices, where W ?{C?, Mu, Lu, H?d}.Finally, we determine the ?-dual of the space H?dand ?(bp)- and ?-duals of the space Hrd. © 2024, Comenius University in Bratislava.
