[sage-devel] element in quotient module
I encountered the following problem: s is the trivial submodule of quo, where quo is a quotient module of modular symbol subspace. The zero element b of quo should be an element of s, but sage says no when I do the following process: # create modular symbol subspace sage: S = ModularSymbols(Gamma1(13),2).cuspidal_subspace() # create the quotient module sage: ker = S.module().subspace([0]) sage: quo=S.module()/ker # now we have the submodule of quo sage: s = quo.submodule([]) # we get zero of quo in the following way sage: a = (0,0,0,0,0,0,0,0,0,0,0,0,0,0,0) sage: aa=S.module()(a) sage: b=quo(aa) sage: b in s it gives FALSE Anybody has any idea where I am wrong?

[sage-devel] Re: ulimit issues and IPython 5.0
Not sure either, but I changed the file. Anyway, probably the issue had to
do with the number of open files. I added the following lines in
limits.conf:
root soft nofile 655360
sage soft nofile 655360
root hard nofile 655360
sage hard nofile 655360
(sage is the user owning sage notebooks). After a reboot the 7.6 notebooks
work OK.

[sage-devel] document Paley construction & special matrices
There's an (old) ticket with code for special matrices that could be merged soon, if someone who knows about *Paley matrices* can continue with the doc + some example ! See: https://trac.sagemath.org/ticket/13703 for further info. I've added the special matrices file (special.py) to the html reference manual. It could be an opportunity if you need to add other famous or commonly used matrix templates.

Thanks for your installer, I rarely works on w10 but recently I wanted to show sage to a friend who has only windows.
