The paper continues the investigations of the sensitivity of the equilibriums for the Cournot competition with uncertain market capacity. There are two types of agents - stubborn and flexible, and two types of interactions - with and without communications. The main idea was based on a calculation of the sensitivity of the equilibriums to control. The equilibriums depend on beliefs of agents about market capacity and their beliefs about the beliefs of other agents. We have calculated the sensitivity of the equilibriums separately for each combination of types of agents. This paper focuses on a mixed case - when there are at least four clusters - each cluster for every combination of types of agents and their interactions.
