Example 1.
First we initialize a 5-dimensional Lie algebra.
We can use the command Query/"Solvable" to check that this is a solvable Lie algebra.
Now we calculate a basis with the ascending ideals property.
The following two commands check, for example, that span is an ideal in span .
The command Query/"AscendingIdealsBasis" will verify that the basis B has the ascending ideals property.
The ascending ideals property becomes apparent if we re-initialize the Lie algebra using the basis B (using the command LieAlgebraData).
