Summary:  We compute all the quantum symmetries of a graph with n disjoint loops at the critical inverse temperature in the sense of [14]. We show that the set of non-isomorphic CQG's appearing as quantum symmetry at the critical inverse temperature has a one to one correspondence with the set of partitions of the number of vertices.
