[GAP Forum] Subgroups of given index of SmallGroups

[Gabriel Bartolini]

Dear GAP Forum,

Is there a way (similar to SubgroupsOfIndexTwo) to list all subgroups of a given index?
I've tried the following which is not too useful. 

F:=Image(IsomorphismFpGroup( G ));
LowIndexSubgroupsFpGroup(F, 4);
[ Group(<fp, no generators known>), Group(<fp, no generators known>) ...

Any suggestions?

Best,
Gabriel
