Sage Interactions - Groups
This page was first created for Google Summer of Code by Alexis Newton, with mentorship by Mckenzie West.
If you have group-related interactions that you are interested in adding to this page, please do so. You can also contact Alexis Newton at firstname.lastname@emory.edu.

Calling Individual Groups from GAP

Group of Order n
Call group order n

Calling a List of Groups from GAP
explanation
Groups Order Less Than or Equal to n
You can use this interact to call all the lists from the GAP library that are order less than or equal to your desired value.

Groups Order Between m and n
You can use this interact to call all the lists from the GAP library that have order between m and n
