What differs, by the numbers

9 of the compared properties differ. Counted from each edition's own definition, so this holds whether or not anyone has written the differences down.

Counts come from each edition's own definition. A zero means the definition records none — for a stub or partial edition that may mean nobody has described it yet rather than that the machine lacks it.
