Dear Gap-Forum,

if I remember correctly, then CAYLEY used to have a very fast function
which computed the normalizer of a permutation group on the letters
[1..n] inside the symmetric group on these letters.

Is there a substitute for this in GAP? Something like

s:=SymmetricGroup(n); ng:=Normalizer(s,AsSubgroup(s,g));

works in general already unusably slowly already for n>25.
