Abstract
‘Good’ subsets The following problem was posed in a recent mathematics contest: Problem. Consider all threeelement subsets of the set SSSS given by Call a subset ‘good’ if the sum of its elements is a multiple of SS. Thus, SSSSSS SSSS SSSS is good, but not SSSSSS SSSS SSSS. Find the number of good threeelement.
