[GAP Forum] Retrieving group name

Try IdGroup.

As far as I know, "most" of the groups have no canonical name. Maybe, if you
are interested in a particular class of groups, something could be
arranged. Let us know. Let us also know in which way do you want to use the
strings like "Q8", and maybe we could suggest you something else for your
problem.
