Supersoldier/Level 1/Room 3

There is a keypad by the door. 
The door is locked, and the keypad has a maximum input length of twenty digits, random guesses won't help. You need to find the password to get in.
The ladder is to your right (go up), the door (Go) back to where you began is to your left, and there is a door (go through) behind you.
