GCC-10 isn't even released yet. Sometimes, if you want to get anything
done, you just have to let people drink bleach.

Yes, exactly. Thank you Eric.
I could compile pillow now, but still, ecl won't work.

This is awesome! Thank you very much, that was really helpful.
Soon, I will open another thread about polarization.

Wow, thanks Vincent. This is awesome! Could you shortly explain what the
crucial difference is here?
On this occasion, may I ask you a slightly off-topic question? Is there an
effective way to compute the polarization of homogeneous polynomials in
Sage?

: seq_taylor = seq.taylor(*inp, n // 2)
sage: Sym.e().from_polynomial(P(seq_taylor))
This code is to compute Todd numbers up the the 6th degree and takes hours
of computation. Did I do use symmetric functions wrong here?

this is a special case they consider, which makes the
computation probably faster.
Kind regards

However, the implemented algorithm seems to be very slow. I know that there
are quite efficient algorithms out there, but are they accessible in Sage?
Thanks for your help and best wishes

Oops, that should be assume(n > 0), but it doesn't change anything else.

Yeah, that's what I tried, and it overwrites the parent method's docstring.

Damn it. Then I another question: Would it cause a slow-down if I
overwrite the method with something like
