Comment (by ncohen):
Hellooooooooooooo !!!
God, I had completely forgotten this patch ! I wrote it more than one year
ago ! `:-P`
If we are to merge it eventually, it would be nice to reuse the plot
method of Braid Groups : #14533. They are prettier, and already in Sage !
I will write a patch to change that, but first could you tell me what you
changed in the Felsner encoding ? I don't see it in your review patch.
This encoding is only useful to prove that the number of such arrangements
is in `2^(n^2)`, but it is cool to have around `:-)`
You are right that in your example all three should be equal, and I will
fix that too. But really this class isn't made to work with pseudolines
yet.. There is just a couple of methods to go from one encoding to the
other, so a meaningless equality is not really a problem.
Have fuuuuuuuun ! And thank you again ! I'll write the additional patch
when I will get your answer `:-)`
