Installed groups aren't really tracked. You can get a list of packages
installed using rpm -qa. You could do something tricky with the output
to coalesce some of the packages into groups using the group definitions.
You'd need to be precise as to what you mean by having a group installed
as groups have three kinds of packages (required, default and optional)
and there a few reasonable definitions as to what it means to have a
group installed.
