Gets an unusual arrangement of factors
I believe the answer is:
agents
'arrangement of factors' is the definition.
'agents' can be an answer for 'factors' (I know this). I'm unsure of the 'arrangement of' bit.
'gets an unusual' is the wordplay.
'unusual' indicates an anagram.
'gets'+'an'='getsan'
'getsan' anagrammed gives 'AGENTS'.
Can you help me to learn more?
(Other definitions for agents that I've seen before include "travelling salesmen" , "They act for others" , "They operate on behalf of others" , "Sales reps" , "Instruments" .)
