Is there an easy function in mathematica that generates a set/list that
consists of r-combinations or r-permutations with replacement?
e.g. I want the set of all possible sets with 3 elements, with entries from
{1,2,3,4}, and also the set of all possible unordered sets with 3 elements,
with entries from {1,2,3,4}.
Any help is appreciated,
-Philip Lu
