I have no idea what that band did, but it's easy to think of a
way to produce 120 different extents: simply add a pair of adjacent
places anywhere in a course, and repeat. There are two possibilities at
each of the 60 changes of a course, giving 120 different extents. And
there must be many more complicated ones possible (including, of
course, the well known ones with four of the usual singles).
