In the layered representation of the MathOverflow DCN, there are three windows with \({\tilde{\beta }}_1 > 20\). Here we depict the weak components contributing nontrivial homology in dimension one for each of these windows. Node labels indicate user IDs; subscripts indicate bins within the window. Essentially, the dynamics here are that groups of users answer multiple questions within a window in a way that overlaps. As the network matured and diluted, this tightly coupled behavior disappeared almost entirely
