We present a new method for approximating the partition function of 2D Ising models using a transfer matrix of order 2". For n=30 our current program took about 20 s on a Sparc station to obtain four correct decimals in the top two eigenvalues and 5 rain for six correct decimals. Eigenvectors were c
