Okay, using the init.sage file with "gap._eval_using_file_cutoff = 10"
seems to work now. Thanks.
Have a new question, which should perhaps go somewhere else, but I'll try
asking here. When I execute
the gap command "SaveWorkspace("MyWorkspace");" in a sage notebook, I get

Hello,
I am new to Sage and I want to use it to solve non-linear systems, used to
model physical phenomenons. I unfortunately met some problems trying to solve a
non-linear system composed of 3 polynoms (2nd order)
I first successfully solved the linear problem, but when I try with the
non-line
I'm in the lab now experimenting. Executing
gap._eval_using_file_cutoff = 1000
in sage mode in a notebook does solve the problem. However, putting this
line in
a file named init.sage in the .sage directory does *not* work.
The lab guru here suspects that sage is not finding the init.sage

Just gap.eval, I think.

Ahh. Thanks for tracking this down.

Not easily. You can use matplotlib to do it directly (

Just to clarify, Ivan means that at the top of the worksheet you could do
%auto
gap._eval_using_file_cutoff = 1000
Of course, you'd have to be in "sage" evaluation mode to do this, not
"gap". This might be a good workaround.
Another possible workaround might also be to just indent less, though

Consider this sequence:

Is there any command like:

I want to do some computations with multivariate polynomials in the group W
of type H4 (14400 elements). I have a summand for every element w \in W,
and a product of 4 polynomials in each summand:
gens = []
for obj in gens_objects:
