This is a temporal network of interactions on the stack exchange web site Math Overflow. There are three different types of interactions represented by a directed edge (u, v, t):

- user u answered user v's question at time t (in the graph sx-mathoverflow-a2q)
- user u commented on user v's question at time t (in the graph sx-mathoverflow-c2q)
- user u commented on user v's answer at time t (in the graph sx-mathoverflow-c2a)

where edges are separated by a new line and

`SRC`: id of the source node (a user)`TGT`: id of the target node (a user)`UNIXTS`: Unix timestamp (seconds since the epoch)
