Let T = (V,A) be a tournament. With every subset X of V is associated the subtournament T[X] = (X,A ∩ (X ×X)) of T, induced by X. The dual of T, denoted by T*, is the tournament obtained from T by reversing all its arcs. Given a tournament T'=(V,A') and a nonnegative integer k, T and T' are {-k}-hemimorphic provided that for all X ⊂ V , with │X│= k, T[V-X] and T'[V-X] or T*[V-X] and T'[V-X]are isomorphic. The tournaments T and T' are said to be hereditarily hemimorphic if for all subset X of V , the subtournaments T[X] and T'[X]are hemimorphic. The purpose of this paper is to establish the hereditary hemimorphy of the {-k}-hemimorphic tournaments on at least k + 7vertices, for every k ≥ 5.
