A graph is focal if the stabiliser of every vertex x fixes exactly one edge not incident with x. It is shown that the problem of testing whether a connected bipartite graph is focal has the same complexity as the graph isomorphism problem. Several other similar questions are also considered.

A chemically and graph-theoretically relevant problem is that of determining whether a pair of graphs G and G' are isomorphic. A two-stage computational test is developed. In the first stage an "eigenvalue-eigenprojector" tabular graph-theoretic invariant is computed, whence if the two tables differ
