These four packages seem to be working fine now. I just copied their source (+quagroup) into the "pkg" directory. I also had to issue gap_reset_workspace() in sage. I'll do more extensive tests later, but for now all these packages seem to be fine. Thanks for your help. On Saturday, September 1

How can I tell if the package I need is safe to add or not? These are the ones I'd like to add for now : gbnp,sla,corelg,repsn; are these safe? if they are, what's the recommended procedure with sage-7.3? On Saturday, September 10, 2016 at 2:41:35 PM UTC-7, Dima Pasechnik wrote: > > > > On Saturd

This is not a good idea to install all GAP packages, if you don't want to break your Sage install. Not all GAP packages are compatible with libGAP (namely, ones that use GAP's dynamic loaded modules, e.g. IO); that is, installing them will break libGAP (and everything that uses it in Sage, which

In mathematica, there is the function "together" which combines fractions by giving them a common denominator and then cancels out the factors. It is shown here: https://reference.wolfram.com/language/ref/Together.html In Sage, I would like to do something similar. I just want to do A,B = var("

Thanks, this is definitely simpler and it worked, but only about half of the packages I use are included. How would I add the other ones? I think these days diskspace isn't much of an issue, it would be nice if there are similar commands to install all accepted packages. On Saturday, September 1

I just built sage-7.3 under Centos7. Everything seems to have worked well : sage comes up fine and a few simple calculations work. The gap part on its won also comes up and works with simple tests, but there are no packages included. I'm now trying to add all the gap packages to the gap componen
