| Abstract: | A permutation group  on a set  of (infinite) cardinality  is almost disjoint if no element of  except the identity has  fixed points, i.e., if  is an almost disjoint family of subsets of  . We show how almost disjoint permutation groups can be constructed from almost disjoint families of sets. |
