The Impossibility of Double Gallows

...
Does this count spaces? And if so is there some way of representing spaces on the graph? Such as colour coding?

The thing is, not only do gallows almost never occur next to one another, relatively few words have two gallows. Thus the space between two gallows is based on the space between their occurrences in adjacent words. Given that gallows also uncommonly occur at the end of words, the common minimum would be something like: [Gy.G].

Yes, it counts spaces. Filtering the spaces separately is difficult with bash - scripts Otherwise you could possibly put them as layers over the diagram.

@Davidsch mentioned his earlier investigations. Maybe he has something to offer?
