A single set of salt and pepper shakers come to mind. But if you collect salt and pepper shakers, you would have a group of salt and pepper sets.

The words set and group have slightly different meanings, even if the difference is somewhat nuanced.
a group is a set with an operation that satisfies the following constraints: the operation is associative and has an identity element, and every element of the set has an inverse element.

You guys are making me go back to my number theory/language theory class days.
