The energy of the system is defined by the interactions between the spins, and the goal is to evaluate the partition function Z, which encapsulates the statistical properties of the system. By considering all possible configurations of the spins and their corresponding energies, we arrive at the expression for the partition function, which in this case is Z = 4e^(4J\u03b2) + 12e^(-2J\u03b2)."}
