When K is a finitely-presented Lie algebra, the GAP operation
IsomorphismSCTableAlgebra can be used to make the structure of K
explicit, in the form of an isomorphic algebra given by structure
constants, which is much more amenable to further computations.
This GAP package installs an alternative method for this operation,
which calls an external C program (fplsa version 4.0) to do the hard
part of the computation. This speeds up the calculation and permits
larger problems to be attempted. The external program has much
additional functionality which is not used by the present version of
the package.
