Hi Dan, Nicolas, Jean, Jason, Martin, ...
This is now implemented. I also added a section on the Lusztig involution
to the thematic tutorial. Everything is posted on trac and the sage-combinat
server. Hopefully this is now close to being finished!
Best,
Anne

Thanks Jean! It's great to have experts with many different points of
view around :-)

I was going to suggest making it a method of ClassicalCrystals (so
it would be available for other crystals besides crystals of
tableaux). However I see that Classical Crystals are no longer a
class but a category, so I don't know how this would work. For
example your E6 or F4 crystals.
That would be as easy as before: just throw the method in the class:
sage.categories.classical_crystals.ClassicalCrystals.ParentMethods
Another comment would be that this might be worth adding doc to in
the thematic tutorial.
Since this method should eventually be moved to root systems (if not
in DynkinDiagram!), I would not advertise it at this point. Or did you
mean doc about the Schützenberger involution?
Cheers,
Nicolas
