The lpres package provides a first construction of finitely L-presented
groups and a nilpotent quotient algorithm for L-presented groups. The
features of this package include:
- creating an L-presented group as a new gap object,
- computing nilpotent quotients of L-presented groups and epimorphisms
from the L-presented group onto its nilpotent quotients,
- computing the abelian invariants of an L-presented group,
- computing finite-index subgroups and if possible their L-presentation,
- approximating the Schur multiplier of L-presented groups.
