I'm always needing to learn more about GAP. Can anyone help me on the following question? Question: I have a list of 500 sublists where each sublist consists of six groups. Is there a command to display or renumber only those sublists with trivial intersection? Is there a function in GAP can solve this?

This questioning arose when I studied a problem on coverage of finite groups.

    This is off-topic here, I think. Why not ask it in the GAP forum instead? http://www.gap-system.org/Contacts/Forum/forum.html2011-01-16
