Dear Gap users:
I wish to find the normalizer of a subset T of a group G,
where T need not be a subgroup. For example, say
G:= Group(a,b,c,d); # a,b,c,d permutations,say
T:= [a,d]; # a subset of the generating set # -- perhaps not quite a legitimate # data structure, # but you get the idea Note that T is not the subgroup generated by a,d . Nevertheless, I want
N:= Normalizer in G of T
How do I proceed? My apologies if I have missed something obvious
in the documentation. Thanks for your advice.
