Abstract: Transfer matrix calculations of the critical two-point correlation function in 2D Ising model on a finite-size$\sqrt{2} L\times \sqrt{2} L$lattice with periodic boundaries along 〈11〉 direction are extended toL = 21. A refined analysis of the correlation function in 〈10〉 crystallographic direction at the distancer = Lindicates the existence of a nontrivial finite-size correction of a very small amplitude with correction-to-scaling exponentω
