Revision: 3557
Log message:

      1. Changed the representation of cyclic subgroups; it looks more
         natural now.
      2. Updated the definition of cyclic subgroups. Since "eqG" was added
         to the def. of groups, the def. of a cyclic subgroup must give the
         description for "eqG" too.
      3. Updated all rules and reproved them.
      
      The same problems as in subgroups exist here also. Will fix soon.
