Query: The Cluster Substructure - Alignment Connection   Using the APM cluster data we investigate whether the dynamical status of
clusters is related to the large-scale structure of the Universe. We find that
cluster substructure is strongly correlated with the tendency of clusters to be
aligned with their nearest neighbour and in general with the nearby clusters
that belong to the same supercluster. Furthermore, dynamically young clusters
are more clustered than the overall cluster population. These are strong
indications that cluster develop in a hierarchical fashion by anisotropy
merging along the large-scale filamentary superclusters within which they are
embedded.
