You have 7 generals and a safe with many locks. You assign the generals keys in such a way that EVERY set of four generals has enough keys b/w them to open ALL the locks; however, NO set of three generals is able to open ALL the locks. How many locks do you need, and list how many keys the first general gets, the second, .... Is there more than one way that works? Passed on by Travis (ferris99@bellsouth.net)
