I don't, but for 3x3x3, I use software: Cube Explorer by H.Kociemba
http://home.t-online.de/home/kociemba/cube.htm

Here are some move sequences I get:

* D L2 B2 F2 R2 U' L2 . F L2 B2 R F2 D' U R2 B L2 R2 B R2  (20 moves)
* U2 F' L2 B D2 B F' U2 . R' B D R' F' L R U' F' L2 R U'  (20 moves)

Just apply them on an already-solved cube.
