[Abstract]
 Here we give the complete characterization of polynomials as a solution
 of the symmetrical diffrence-functional equation, generalizing the
 well-known Lagrange equation. The key notion is the conjugation by the
 linear transformation. 

[Keywords]
 generalized means, difference-functional equation
