as far as I know there is no user-group sysop, because

sysop-user per wiki-installation.
no, you can add new sysop-users (and there is a sysop group)
To add a new sysop, you must either
* log in as a bureaucrat (WikiSysop) and go to the page [[Special:Userrights]] of your
wiki.
or
* use the ./maintenance/createAndPromote.php function
or
* change something in your mysql database (not a recommended solution though)
In my wiki-installation the sysop-user is called
WikiSysop (which I think is the
default). This user appears in special:userlist, but is not denoted as sysop.
In my install, it is denoted as
* Wikisysop (Bureaucrat, Sysop)
