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 ]
