The floors of the Brown CS department are roughly square. Most offices have a window to the outside. A few windowless offices, classrooms, meeting rooms, etc., are in the inside of the building, which is organized in square or rectangular blocks.
Some of the new PhD students complained about the numbering system for the offices: offices that are contiguous or that face each other do not necessarily have contiguous or near-contiguous numbers.
How can one number offices to avoid this problem?
