Some coordinate transformations on two variables are obtained that give a realization of the cyclic group. The differential invariants of scaling transformations are then combined to give quantities that are multiplied by a complex root of unity when the cyclic transformations are applied. The secon

Discrete analogues of the Painleve equations have recently been derived using either a method based on orthogonal polynomials or the singularity confinement method. Here we analyze additional methods for deriving integrable nonautonomous discrete equations. These methods are based on the discrete AK
