Arrgh, I had my google account settings wrong and several of my email
posts went to the
bit bucket before I noticed.
I have been encountering doctest errors involving the availability of
chevie:
/coxeter_group.py", line 256, in CoxeterGroup
assert is_chevie_available()
What is the workaround?
The error log follows (snipped after the assertion error).
(Note that _test_enumerated_set_iter_cardinality() also fails.)
