Summary: A Mathematica\(^\circledR\) package for finding Lie symmetries of partial differential equations is presented. The package is applied to perform a full Lie group analysis of basic models of nonlinear fiber optics. As a result of this, group invariant solutions are obtained. Comparisons with earlier published computer algebra implementations of the Lie group method are discussed.For the entire collection see [Zbl 1154.17001].
