Abstract
Complete expressions of all even correlations for the triangular Ising model in a recent exact evaluation of P(h,T), the local magnetic field distribution, are obtained from the Pfaffian representation derived by Stephenson. The results for the ferromagnetic JJ>0 cases contain a number of interesting features previously not pointed out in the Ising literature. As a bonus, some new inequalities relating odd and even correlations are also obtained.Keywords
