Abstract.
We show the consistency of \({\frak o} <{\frak d}\) where \({\frak o}\) is the size of the smallest off-branch family, and \({\frak d}\) is as usual the dominating number. We also prove the consistency of \({\frak b} < {\frak a}\) with large continuum. Here, \({\frak b}\) is the unbounding number, and \({\frak a}\) is the almost disjointness number.
