I have taken the first permutation algorithm I found in wikipedia and implemented it in Delphi (2009); I hope that is what you are looking for:
type
TIntegerArray = array of Integer;
procedure Permutation(K: Integer; var A: TIntegerArray);
var
I, J: Integer;
Tmp: Integer;
begin
for I:= 2 to Length(A) do begin
J:= K mod I;
Tmp:= A[J];
A[J]:= A[I - 1];
A[I - 1]:= Tmp;
K:= K div I;
end;
end;
procedure TForm1.Button1Click(Sender: TObject);
var
K, I: Integer;
A: TIntegerArray;
S: string;
begin
Memo1.Lines.Clear;
for K:= 0 to 719 do begin
A:= TIntegerArray.Create(14, 2, 4, 5, 6, 8);
Permutation(K, A);
S:= '';
for I:= 0 to Length(A) - 1 do
S:= S + Format('%3.d ', [A[I]]);
Memo1.Lines.Add(S);
end;
end;
solved All array possibilities
