Comment (by fuglede):
Fixed the issue in my previous comment with some refactoring to force sage
to stay out of the field of fractions of the polynomial ring whenever
possible. Even though this appears to require
[http://git.sagemath.org/sage.git/tree/src/sage/groups/braid.py?id=1b50612c99d13120a876ee95a4b79fa1008b7d45#n938
some silly manipulations], this even resulted in a speed gain: the 2961
knots mentioned earlier can now be checked against known data in 38
seconds (down from 69 seconds).
So, what's the process: should I flag as needs review?
