Oh, I'm sorry having sent you that link, apparently I have it in the
exception list ...
However, you can get the current handbook from github if you are interested:
You'll find the examples on page 66 ff.
Concerning ordering you're right that it may be depending on implementation
(but this has to be clearly documented, e.g. implicit ordering).. My
understanding is that we either are dealing with vertex sets (as Waldek
suggested) or otherwise, if explicit orientation is a concern then we ought
to use chains, e.g. integer chains [1,2]=-[2,1].
