  We study the Ising model on $\mathbb{Z}^{2}$ and show, via numerical
simulation, that allowing interactions between spins separated by distances $1$
and $m$ (two ranges), the critical temperature, $ T_c (m) $, converges
monotonically to the critical temperature of the Ising model on $\mathbb{Z}^4$
as $ m \to \infty $. Only interactions between spins located in directions
parallel to each coordinate axis are considered. We also simulated the model
with interactions between spins at distances of $ 1 $, $ m $ and $ u $ (three
ranges), with $ u $ a multiple of $ m $; in this case our results indicate that
$ T_c(m, u) $ converges to the critical temperature of the model on $
\mathbb{Z}^6$. For percolation, analogous results were proven for the critical
probability $p_c$ [B. N. B. de Lima, R. P. Sanchis and R. W. C. Silva,
