### subsets with condition

given a collection say ([(0, 1), (0, 2), (0, 4), (3, 5)],[(0, 1), (0, 2), (0, 5), (3, 4)],[(0, 1), (0, 4), (0, 5), (2, 3)],[(0, 2), (0, 4), (0, 5), (1, 3)],[(0, 1), (1, 2), (1, 5), (3, 4)] }

How to obtain subset or sub collection say size 3 or as specified by user such that intersection between (first internal set and second internal set) is one set and (first internal set and Third internal set) is zero sets ,(second internal set and Third internal set) is one set . That is like ([(0, 1), (0, 2), (0, 4), (3, 5)],[(0, 1), (1, 3), (1, 5), (2, 4)],[(0, 4), (1, 3), (2, 5),(4,5)]

The number of intersection between sets in each to be specified by user. How to do without enumerating all subsets any hint.
