Comment(by stumpc5):
Replying to [comment:8 chapoton]:
I really appreciate that you do some progress on these patches, thanks!
I think I will reimplement this patch using subword complexes rather than
the cluster implementation. This will be much faster, and I don't expect
that the cluster package will become part of main sage soon (see the
dependency above). On the other hand, the subword complexes depend on my
new implementation of finite reflection groups (#11187) which depends on
the implementation of the universal cyclotomic field (#8327), so it will
also be unlikely that it will get positively reviewed soon (and I see that
all of them have rejects in the newest versions, so it will be an even
longer way).
> 1) type A_n is in n+3 sided polygon
> 2) formatting of doc is not correct in cartan_type
I will update the patch fixing these issues.
Best, Christian
