[GAP Forum] Creating all subgroups of SymmetricGroup

[Могильных Иван Юрьевич]

Hello, GAP forum!
Can I create the set(list/ record) of all subgroups (preferebly
nonisomorphic) of a Symmetric Group on 9 elements - Sym(9)?
There is a function IntermediateSubgroup(G,U) which creates all subgroups
"between"G and U.
But this record contains additional information and GAP is working too slow
while trying to create it.
Can I boost it somehow?
