Comment:
You're right. I turned the comments describing how to compute the
precomputed things into docstrings. Unfortunately they don't seem to work
anymore. The line
{{{
sage: Psi5 = sum([X**i * f.coefficient({x:i})(X,t) for i in
range(3)]).monic()
}}}
fails with
{{{
AttributeError:
'sage.rings.polynomial.multi_polynomial_libsingular.MPolynomial_libsingular'
object has no attribute 'monic'
}}}
Can this be fixed easily?
