This link shows the Arch sagemath package info that I installed
https://archlinux.org/packages/extra/x86_64/sagemath/
There is link at bottom of this page to show list of all files also (click
on package content)
I see number of files with giac in them. Here is the list from my linux
using the command you gave
>pacman -Ql sagemath | grep -i giac

That is all. I see the file
/usr/lib/python3.13/site-packages/sage/libs/giac/
Is this the giac sagemath 10.5 is using then? If so, how to find
the version of giac it is using?
It would be much better if it is using the system giac, but I am still not
sure
which giac it is using.
Will see if I can find more information.
