Abstract
The renormalization-group transformations for a square Ising spin lattice are evaluated in a four-cell-cluster approximation to obtain the critical surface in a three-dimensional space of spin-interaction parameters. Agreement is found with known critical curves, particularly Baxter's analytic solution.Keywords
