Table 2 Main mathematical features of rational solutions \(u_{n}\) and \(v_{n}\) of order j

From: Dynamics of bright and dark multi-soliton solutions for two higher-order Toda lattice equations for nonlinear waves

j	HPN	HPD	Background
1	6	6	1
2	20	20	1
3	42	42	1
…	…	…	…
j	2j(2j + 1)	2j(2j + 1)	1

Here, HPN is the highest power in the numerator, while HPD is the highest power in the denominator.
