Comment(by drkirkby):
Is there any explanation of why these doc tests need to be revised? I can
see
sage/symbolic/expression.pyx
has a pretty trivial change, since Magma has decided to reverse the order
of the outputs.
But others seem really odd.
magma(HyperellipticCurve(f)).IgusaClebschInvariants() # optional - magma
remove: [ 0, -2048/375, -4096/25, -4881645568/84375 ]
add: [ -640, -20480, 1310720, 52160364544 ]
Were the first set of Magma results wrong? If so, why was they used as a
doctest?
This is probably my lack of mathematical knowledge showing here, but it
appears to me Magma has output something completely different in many
cases. Is the new output correct? Was the old output incorrect?
