Nature of problem:
Determination of analytical properties of systems of differential equations, including symmetry transformations, analytical solutions and conservation laws.

Solution method:
The package implements in MAPLE some algorithms (discussed in the text) for the study of systems of differential equations.

Depends strongly on the system and on the algorithm required. Typical restrictions are related to the solution of a large over-determined system of linear or non-linear differential equations.

Running time:
Depends strongly on the order, the complexity of the differential system and the object computed. Ranges from seconds to hours.
