Abstract The Ising model with exchange integrals ± J for a square lattice spanned over infinite length tubes of the width of 2, 3, or 4 bonds is considered. The paper gives a short description of a method of linear equations allowing a reduction of a physical problem of determination of e.g. energy, entropy, magnetisation for systems with frozen disorder, to a solution of a system of linear equations. The results for energy, entropy and magnetisation possible for a short presentation are given.
