Subj : ordered subset question To : comp.programming From : John Trunek Date : Mon Aug 01 2005 01:34 pm I need to obtain all the ordered subsets of containing 7 elements from a list of 15 elements. From what I remember, the number of ordered sets is given by the formula numOfSets = 15! / (15-8)! = 32,432,400 Unfortunately, I'm not familiar with permutation algorithms. Could someone please point me in the right direction to solve this problem? John .
