分别取连续实值和任意整数值，得到了具有两种自旋变量的伊辛型模型的星-三角关系的新解。博尔兹曼的权重显然是真实和积极的。它们通过Euler Gamma函数表示，并取决于晶格边缘末端的自旋总和和差。
We obtain a new solution to the star–triangle relation for an Ising-type model with two kinds of spin variables at each lattice site, taking continuous real values and arbitrary integer values, respectively. The Boltzmann weights are manifestly real and positive. They are expressed through the Euler gamma function and depend on sums and differences of spins at the ends of an edge of the lattice.
