A new and distinct Sutera cultivar named \u2018DANCOP28\u2019 is disclosed, characterized by having a compact, semi-trailing growth habit, and a very well branched, ball-shaped plant. A set of reference symbols associated with a reference signal are allocated, and a base sequence is generated. A difference result set is determined according to a difference between items in the primary result set and second result set, which is displayed to a user. The holdout rings are rotatably connected at their remote ends with the clutch members by integral annular outer ribs that extend within corresponding grooves contained in the counterbore wall surfaces.
