I am in trouble as I cannot find no way to obtain an ordered subsets of k elements with mathematica 5.2.
I didnt find any solutions...Mathematica
seems hadle just Permutations (n=r) or unordered subsets of k elements (KSubsets)as built-in functions. What I want is what is explained here
(http://mathworld.wolfram.com/Permutation.html) at the 8th text row ...but no Mathematica function is showed :(
Please note I dont want just the "number" of total rearrangements but I want
a named list of all subsets of k elements
Any solutions? I hope yes...
