abstract="The evolution of a group's network structure is charted in a way that extends earlier discussions of this phenomenon. Comparisons are made between the uses of sliding and expanding windows for hypothetical and real data. These comparisons suggest that, generally, the sliding window is preferable. Additionally, the Q-analytic tools used earlier to chart network evolution ignore the internal structure of equivalence classes. This internal structure can be delineated in terms of cliques, n-cliques and betweenness centrality. Of these, the first and third seem the most useful, with betweenness centrality having the greatest potential for an interpretable measure of internal structure.<p />",
