The codes to the Domes change every time you start a new game so I can't tell you what the code is but I can tell you were to find It.First you must go to Crater Island(boiler Island). Once you have found The Laboratory on top of the hill you must read through the journal that is on one of the desks. In it you will find the dome code for that game but it the D'ni language. So then you write them down and go to the section on my page called "The D'ni Number System" and figure out the code from there!

Good Luck!
