I'm looking for a pair of words that essentially means "super-collection" and "collection" where the super-collection contains a set of collections. (Alternatively, could be thought of as a "collection" which contains a set of "sub-collections".) I want the words to NOT use either "super" or "sub". I'm open to general English or jargon from specific domains.
Example usage:
Ok, we've got five _<collections>_ – let's group them together into a _<super-collection>_.

This question asks for abstract collective nouns that have an intuitive hierarchy, with one word each for what in mathematics would be called a "set" and "set of sets."
Approach 1: Use a collective noun with a suffix for the second "set of sets" term in order to emphasize the higher-order act of bringing-together.
Approach 2: Use a more specific collective noun for the set, and a more general for the set of sets. The question is carefully phrased to avoid the domain of the set items / objects, however if there is a domain then this would be a good strategy.
