In the Samsung Galaxy Tab, you can put a passcode to protect it. There are 9 dots on the passcode. You have to connect at least 4 dots to make a combination password. How many passcodes can you make? Details: 1. If you try to connect one corner to another corner, it counts as THREE dots. This is because there is a dot in between. 2. Order DOES matter. 3. Have fun! This is a problem I have thought about for a few days, but have no idea where to start.
