How do I finish the room with many useless doors (mausoleum)?

Question

I found a room with about 50 doors arranged in four rows of four on each side of the cube, but with some removed/blocked. Every door I have gone through has brought me to a different door in the same room, but the world map shows that there is an exit to another room.
