Abstract
This Note deals with the pairs of binary relations which have the same basis and which the 3-element restrictions are isomorphic and those o f 5-element restrictions are isomorphic or anti-isomorphic. We obtain a decomposition of this relations in classes that we will characterize . As application, we give the threshold of half-reconstruction for tou rnaments.
