摘要
A homogeneous family of subsets over a given set is one with a very 'rich' automorphism group. We prove the existence of bi-universal element in the class of homogeneous families over a given infinite set and give an explicit construction of 2(2 aleph 0) isomorphism types of homogeneous families over a countable set.
