    The authors announce a new three-stages symmetric six-step finite difference pair. The numerical experiments obtained by the new developed finite difference pair and the well-known and recently produced pairs to the radial Schrödinger equation are presented. The main contribution of the paper consists of a comparative study of the new finite difference pair with other finite difference pairs of the same family.
