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.
