`liesymm`

is a Maple package that is an implementation of the
Harrison-Estabrook procedure (as outlined in the *Journal of Mathematical
Physics*, vol 12,
American Institute of Physics, New York, 1971, pp. 653-665.). It obtains the
determining equations leading to the similarity solutions of a system of
partial differential equations using a number of important refinements and
extensions as developed by J. Carminati (J.Carminati et al., *J. Symb. Comp.*
14 (1992) 103-120)
