[GAP Forum] A question about generators

Dear Forum,
 I would like to obtain a subgroup which is generated by several subgroups of a given finite group, i.e. the generators of the subgroup are some subgroup, but not some elements.
For example: G:=SmallGroup(200,44);; N:=NormalSubgroups(G);;
If H and K are subgroups  of G, we denote by <H, K> the subgroup generated by H and K. 
What is the subgroup <N[3], N[4]>?
How to express it in GAP?
Best Wishes
LIU
