Thank you Dima and Isuru, creating a new conda environment worked! (I'm
guessing you updated the givaro dependency for the conda install)
And it looks like manually specifying an older version of givaro will also
work, based on Mariusz's report.

hey,
I had similar/same(?) problem as Mike and installing older version of
givaro (conda install "givaro=4.1.1=h192cbe9_1") fixed it.

Mike,
Can you try creating a new conda environment? This is an issue with the
latest givaro build we had and we marked it as broken.
Details at https://github.com/conda-forge/givaro-feedstock/issues/13
(You could also try doing `conda install "givaro=4.1.1=h192cbe9_1"` to get
the older link.)

Having defined `H`, you can type
H.
then hit the TAB key to see what methods are a
How can I calculate the direct product of two groups and/or the direct sum?
For example given:
G.=FreeGroup()
H=G.quotient([x*y])
how do I calculate H+H and HxH?

I've also attached the full output of the nm command as a txt file below in
case it's helpful!

Thanks a lot, I hadn't seen that discussion. It is a shame, but it seems
that github repositories are planned to be allowed, which would work fine
for my purposes.
Best regards,

Hi there,
The trusted Sage Cell server stopped loading external resources, e.g. for
load("https://bitbucket.org/malb/lwe-estimator/raw/HEAD/estimator.py";)
n, alpha, q = 256, 0.0009765625, 65537
set_verbose(1)
_ = estimate_lwe(n, alpha, q)

I suppose you mean the finitely generated Z-module (abelian group)
presented by the matrix, ie. its cokernel. In that case, you can do:
sage: A=matri

Your matrix has determinant 4 - 9 = -5. Hence, the group it generates
in GL(2,QQ) is necessarily infinite.
