In this short note, we draw attention to a relation between two Horn polytopes which is proved in  as a result, on the one hand, of a deep combinatorial result in  and, on the other hand, of a simple computation involving complex structures. This suggests an inequality between Littlewood–Richardson coefficients, which we prove using the symmetric characterization of these coefficients given in .
