Comment (by aschilling):
Please add what the INPUT is in the following methods in the
extended_affine_weyl_group:
apply_simple_projection
coset_representative
face_data
action
translation_group_morphism
simple_reflection
bruhat_le
There are certain methods that occur multiple times with code that looks
only
minimally different (for example in `has_descent` it looks like that only
left and
right have changed). Could you explain why one needs the methods in each
realization
separately rather than having one general one.
Same in src/sage/groups/group_exp.py. There are methods where some of the
input needs to be explained.
