Version vom 12. Oktober 2018, 07:38 Uhr
Sage is a free open-source mathematics software system licensed under the GPL.
Version 7.5.x im Pool
Im Pool und auf den Shell-Servern steht sage ebenfalls zur Verfügung.
Jeder User kann einfach einen lokalen Server starten:

At this point your default browser will open this url.
Terminate the notebook session with Ctr-C and exit sage with quit.
The port=12002 parameter is only relevant on shared sytems to keep concurrent notebooks apart. Otherwise the default (port=8080) is fine.
Version 8.x (Autumn 2018) on sage.informatik
Pre-Announcement:
- xx.09.2018: We'll upgrade to Version 8.x by switching to a new instance on Ubuntu Bionic (18.04). This old instance will vanish in Oktober, so please grab your data while it's available. This will be a new VM. To allow usage of both instances (for a short while) it will use the name "sage" instead of "sage2", so the URL will be https://sage.informatik.uni-goettingen.de
- this is unrelated to the version available in the CIP-Pool which will stay at 7.x as the pool runs on Ubuntu Xenial (16.04) for now
