A practical issue arises from the different tools describing AAMs using their own atom numbering. As a consequence, the results are not trivially comparable. It was only proved recently that the equivalence of AAMs can be reduced to isomorphism of certain auxiliary graphs, notably including the Condensed Graph of a Reaction (CGR), which was introduced much earlier under the name Imaginary Transition State (ITS) as a graph theoretical description of a chemical reaction. The toolkit EEquAAM for comparing AAMs 23 requires stoichiometrically balanced reactions, i.e., AAMs that are bijections between reactant and product atoms.
