Comment (by chapoton):
This sentence is now wrong (in the tutorial):
{{{
The keys are the positive roots, so
given a reflection, you can look up the corresponding root.
}}}
And please add the ref to the ticket 20027 also directly in the modified
function in
`sage/combinat/root_system/weyl_group.py`
