My experience with fplll (used from Sage or directly from C) has been

occurred.
I'm not claiming that the scenario that you laid out could not occur;
I just wanted to clarify what happened in the case in question.

This would my proposal for irreducible_characters(). For

Minh,
when the build is done, can you do a bdist and post the link to the

that just iterate through irreducible_characters(), we are again prone
to breakage at upgrades, etc.
