Comment:
Okay, I made the group smaller (`B_2` instead of `B_3`) which gets rid of
the 400+ seconds. I think we should leave the tests in there. The first
one will always be slow due to making the cache, but is not horribly long
(like 400 seconds!) and allows the other tests to be much faster. And in
case anybody is curious, the Weyl group creation is slow due to loading
(lib)Gap and must be done.
