We study independent families of functions and permutations and associated cardinal characteristics and. In this paper, we show that these cardinals lie between the cardinals and and give some related consistency results.

We consider the possible cardinalities of the following three cardinal invariants which are related to the permutation group on the set of natural numbers: the least cardinal number of maximal cofinitary permutation groups; the least cardinal number of maximal almost disjoint permutation families; the cofinality of the permutation group on the set of natural numbers.We show that it is consistent with that ; in fact we show that in the Miller model.
