Roger,
A. You need 3 items to deduce the codes:
1. The patterns seen on each of the doors in the central tower as well as the one on the east-west passage below.
2. The paper on the wall inside the central tower elevator that has numbers inside the squares.
3. The paper with pattern with ABCDE from Kales' room.
B. Now you superimpose one of the door patterns on the paper with letters. You will note that the pattern crosses the letters ONCE only on ABCDE.
- Note the position of those ABCDE.
c. Now find those positions on the paper with numbers.
This will give you the numbers associated with ABCDE for that specific patter.
So each patter or direction has a code made up of ABCDE and their numbers.
That is what you enter on the panel inside the tower.
