Abstract
The exterior differential form approach for finding Lie-Point symmetries of differential equations is extended by implementing equivalence transformations to the formalism. The implementation is shown on a previously worked example of non-Newtonian fluid flow. Group classification of the equations are performed using this method. (C) 1998 Elsevier Science Ltd.
