Gap groups commands

Question

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.html — Arturo Magidin, Jan 16 '11 at 20:42
coreFreeList := Filtered( list, sublist -> IsTrivial( Intersection( sublist ) ) );; — Jack Schmidt, Jan 17 '11 at 00:08
Thanks Jack Schmidt! This command solved the problem! Thank you very much. — , Jan 20 '11 at 00:40

This question is in fact answered in the comment by Jack Schmidt (thanks!):

coreFreeList := Filtered( list, sublist -> IsTrivial( Intersection( sublist ) ) );;

so I'm just answering it formally to prevent it from appearing in the list of unanswered questions.
