This is a graph whose edges have categorical edge labels. Nodes represent brain regions from an MRI scan. There are two edge categories: one for connecting regions with high fMRI correlation and one for connecting regions with similar activation patterns. Some summary statistics of the network are:

• number of nodes: 638
• number of hyperedges: 21,180
• number of edge label categories: 2
• rank of hypergraph network (maximum hyperedge size): 2
