I looks like the tile of your post was truncated, so I'm not quite sure what you're asking. Here is a shuffle algorithm: shuffle[s_List] := Module[{a = s, f, i, j, n = s // Length}, f[i_] := (j = RandomInteger[{1, n}]; {a[[i]], a[[j]]} = {a[[j]], a[[i]]}); Map[f, Range[n]]; a ]; Perhaps what you want is: ril [ range_Integer] := Shuffle [ Range [ range ] ] Or if you wish an incomplete set of k items, without duplicates: ril [ range_Integer, k_Integer ] := Take [Shuffle [ Range [ range ] ] , k ] HTH On Thu, Jan 17, 2013 at 9:54 PM, <brtubb090530 at cox.net> wrote: > Consider the following: > > ril[range_Integer]:= RandomInteger[{1,range},range] > > This function is almost what I want; but I need one which doesn't include any repeated values.
