A note on the union-closed sets conjecture
Published online by Cambridge University Press: 09 April 2009
Abstract
It has been conjectured that for any union-closed set there exists some element which is contained in at least half the sets in . It is shown that this conjecture is true if the number of sets in is less than 25. Several conditions on a counterexample are also obtained.
