Example 1.
Obtain the indices for the ["Winternitz", 1] table. This table contains a list of all Lie algebras of dimension less than or equal to 5 and a list of nilpotent Lie algebras of dimension 6.
Display the entry for the index [4, 2].
Display the entries for the indices [5, 0]..[5, 5]. We first use the ListTools[Search] command to locate the position of the indices [5, 0] and [5, 5]] in L.
Example 2.
Obtain the indices for the ["Gonzalez-Lopez", 1] table. This table contains a list of all Lie algebras of vector fields in the plane.
To browse this table, one must first define a two dimensional manifold and pass the name of this manifold to the Browse command.
Example 3.
Obtain the number of indices for the ["Kamke", 1] table (The list is too long to show here). This table contains a list of all ordinary differential equations in Kamke's book.
