Show affiliationsThis paper studies the application of the structure theory of infinite-dimensional pseudo-groups to computing symmetries of differential equations. The main tool is a combination of Cartan's method of equivalence and the moving coframe method introduced by Fels and Olver. Our approach does not require a preliminary computation of infinitesimal defining systems, their analysis and integration, and uses differentiation and linear algebra operations only. Examples of its main features are given.
