FGA - Free
Group Algorithms
===========================
A GAP
4 package
Contents:
---------
The FGA
package provides methods
for computations
with finitely
generated subgroups
of free groups.
It allows you
to (constructively) test membership
and conjugacy,
and to compute free generators, the rank, the index, normalizers,
centralizers,
and intersections where the groups involved are finitely
generated subgroups
of free groups.
In addition, it provides generators
and a finite presentation
for the
automorphism
group of a finitely generated free
group and allows
to
write any such automorphism as word
in these generators.
Note that this version
of FGA
is a fork
of the original FGA
package
by Christian Sievers, available at <
https://github.com/chsievers/fga>.
This fork
is maintained by the GAP team
to incorporate various
minor changes.
Requirements:
-------------
FGA
is written
for GAP version
4.
8 or later.
It does
not use external programs
and does
not depend
on
system specifics.
License:
--------
The FGA
package is free software
and can be redistributed
and/
or
modified under the terms
of the GNU General Public License; either
version
2 of the License,
or (at your option) any later version.
For details see the
file COPYING.
Installation:
-------------
The installation follows standard GAP rules.
So the normal way
to install
is to unpack the archive
in the `pkg`
directory, which will create an `fga` subdirectory.
Enjoy!
