Comment (by cremona):
Nils, can you explain the following? Starting with the most recent commit
above, if you make one change to sage/structure/factorization.py
{{{
@@ -319,10 +319,7 @@ class Factorization(SageObject):
self.__unit = unit
self.__cr = cr
if sort and self.is_commutative():
- try:
- self.sort()
- except NotImplementedError:
- pass
+ self.sort()
}}}
then there are many failures, for example
{{{
sage: pol26 = hilbert_class_polynomial(-4*26)
sage: K = NumberField(pol26,'a')
sage: K.optimized_representation()
<boom>
NotImplementedError: root finding for this polynomial not implemented
}}}
