procedure PrintPermutations(words: array of string; n: integer);
var
  i, j, k: integer;
begin
  for i := 0 to High(words) do
    for j := 0 to High(words) do
      for k := 0 to High(words) do
        if (i <> j) and (j <> k) and (i <> k) then
        begin
          WriteLn(words[i], ', ', words[j], ', ', words[k]);
