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 ]
