“…where Poly m (x) denotes the sequence of polygonal numbers (for details please refer to [BPT98]) and proved that for all but a finite, computable set of pairs (m, n), max(x, y) is effectively bounded. In 2012, Dujella, Győry and Pintér [DGP12] studied the power values of pyramidal numbers. Recently, in two papers Pintér and Varga [PV11] and Hajdu, Tengely, Pintér and Varga [HPTV14] used various effective methods to investigate the equal values of general figurate numbers.…”
