Cliques as integral groups (4)
I believe the answer is:
sets
This clue could be a double definition.
'cliques' is the first definition.
(I've seen this in another clue)
'integral groups' is the second definition.
'sets' can be an answer for 'groups' (a set is a group of things). I'm not sure about the 'integral' bit.
'as' is the link.
Can you help me to learn more?
(Other definitions for sets that I've seen before include "Units of play in tennis" , "Solidifies" , "Places" , "Scenery etc. of 11 across productions" , "Plants" .)
