  The problem of finding measures whose orthogonal polynomials are also
eigenfunctions of higher-order difference operators have been recently solved
by multiplying the classical discrete measures by suitable polynomials. This
problem was raised by Richard Askey in 1991. The case of the Hahn family is
specially rich due to the number of parameters involved. These suitable
polynomials are in the Hahn case generated from a quartet $F_1,F_2,F_3$ and
$F_4$ of finite sets of positive integers. In this paper, we show that the
order of the corresponding difference operators can be reduced by assuming
certain symmetries on both, the parameters of the Krall-Hahn family and the
associated quartet $F_1,F_2,F_3$ and $F_4$.
