Hypergraph where nodes are users on MathOverflow and hyperedges are sets of users who answerered a certain question category (derived from different tags involving algebra). The dataset was derived from the Stack Exchange data dump. Some summary statistics of the network are:

• number of nodes: 423
• number of hyperedges: 1,268
• number of edge label categories: 32
• largest degree of any node: 375
