For a given probability distribution lambda (1),aEuro broken vertical bar,lambda (m) we determine the structure of all such maps defined on a dense subset of density operators which leave the Holevo bound invariant i.e. which satisfy Equation for all possible collections rho (1),aEuro broken vertical bar,rho (m) of density operators.
