In this paper, multiple rogue wave solutions of a generalised Hietarinta-type fourth-order equation in (2 + 1)-dimensional dispersive waves were studied by applying the bilinear method. We obtained its 1-rogue wave, 3-rogue wave and 6-rogue wave solutions. Similarly, their corresponding maps which can finely explain their physical structure and properties were graphically shown through symbolic computation approach. It is obvious that the centre of the 3-rogue wave possesses a triangular structure while 6-rogue wave has a hexagon structure and they are made of three and six independent 1-rogue waves, respectively. Furthermore, the results obtained have immensely augmented the exact solutions of the generalised Hietarinta-type equation on the available literature and enabled us to understand the nonlinear dynamic system deeply.
