The lattice sine-Gordon equation is an integrable partial difference equation on ℤ², which approaches the sine-Gordon equation in a continuum limit. In this paper, we show that the non-autonomous lattice sine-Gordon equation has the consistency around a broken cube property, as well as its autonomou...
