Abstract
The general technique for constructing the bi-harmonic operator´s difference analog on a regular grid is being presented. The method guarantees preserving of invariance of the original differential operator with respect to the Cartesian co-ordinate system linear transformations what provides the uniqueness of the analog. The numerical value of 3-order analog has been obtained.
