def total_possible_edges_in_all_comms(self):
return _c_louvain._MutableVertexPartition_total_possible_edges_in_all_comms(self._partition)<EOL>
The total possible number of edges in all communities.

        Notes
        -----
        If we denote by :math:`n_c` the number of nodes in community :math:`c`,
        this is simply

        .. math :: \\sum_c \\binom{n_c}{2}
