All finished BUT my worry is that there does not seem to me to be a unique path to highlight - several possibilities for A's and E's - does anyone agree or disagree?
I looked for such a path too, but found something much simpler to highlight which gives our 'individual' by another term - I may be wrong if it's a coincidence & there's another path.
Snowy_owl, I think mine is the same as yours, but I wasn't good at typing the .... bits! I've no longer got the paper, but I'm almost certain mine was in one part, all words following each other.
