文献中散布着各种概括中值图和中值代数的结构：准中值图、汉明图的缩进、有限windex图、各向同性介质、单纯形代数的次直积、某些三元代数等等。我们将它们全部连接起来，提供了一些新的准中值图的推广、一些新的准中值代数公理集，以及一些更短的证明。
Scattered through the literature various structures occur that generalize median graphs and median algebras: quasi-median graphs, retracts of Hamming graphs, graphs of finite windex, isotropic media, subdirect products of simplex algebras, certain ternary algebras, and so on. We connect them all up, provide some new generalizations of quasi-median graphs, some new sets of axioms for quasi-median algebras, and some shorter proofs as well.
