i tried the following input (as i found it in a tutorial of christian stump):

W=CoxeterGroup(['A',3])

but it does not work (name 'CoxeterGroup' is not defined)

What's the problem with this?

It looks like this might require the sage-combinat queue. Or, it could be an old version of that code?

sage: W = WeylGroup(['A',3])
sage: W
Weyl Group of type ['A', 3] (as a matrix group acting on the ambient space)

It looks like there is more of a hierarchy now, based on the outcome of

sage: CoxeterGroups?
