Hi, I note that python-igraph has the method Graph.triad\_census, which returns the count of each triad type in a graph. I haven’t been able to find a method in igraph which gives all the actual subgraphs (edges & vertices) of each triad type. If it does not exist, are there any plans for future inclusion of such a method? At the moment we are using NetworkX’s ‘triads\_by\_type’ method, which gives quite satisfactory output, however we are looking for an increase in performance. Thank you! ---

It is possible for the _connected_ triads. The [`motifs_randesu()`](https://python.igraph.org/en/stable/api/igraph.GraphBase.html#motifs_randesu) function has a `callback` parameter. Here you can pass a function which will be called with each triad found, and its type (“isoclass”). ---

Thank you! Much appreciated.
