Lie Group theory is applied to the coupled system of partial differential equations. Group classification is performed with respect to the arbitrary filter coefficient. Some similarity solutions are constructed using the symmetries.EnglishAll Open Access; Gold Open AccessMathematical transformationsNonlinear equationsPartial differential equationsGroup classificationFiltrationGroup classification and some similarity solutions for a nonlinear filtration equationArticle10.3390/mca7010001
