Abstract
This paper introduces a generalization of association schemes, for arbitrary finite graphs, even for arbitrary square matrices. This serves several ends: it can help to find eigenvalues, it can decide whether a given graph is the graph of an association scheme, it generalizes the notion of tactical decomposition (in both graphs and designs), and it includes coherent configurations as well.
