Popis:	In this paper, by using the classical Lie symmetry approach, Lie point symmetries and reductions of one Blaszak—Marciniak (BM) four-field lattice equation are obtained. Two kinds of exact solutions of a rational form and an exponential form are given. Moreover, we show that the equation has a sequence of generalized symmetries and conservation laws of polynomial form, which further confirms the integrability of the BM system.
