I am trying to generate partitions of networks to evaluate clustering algorithms. I know that generating all partitions is infeasible (since they grow with Stirling number of the second kind which get big very quickly). I would like to restrict this to partitions that have a minimum size since these are the ones I care about anyway.
As a bonus, if anyone has a good way to estimate the number of such partitions for set size N, number of partitions k and minimum partition size l that would also be appreciated.
