Changes since bug fix 3:
* Interface changes affecting the AutPGrp and ANUPQ packages (these
packages will need reinstallation).
* 24 computational problems (please see the description4 file supplied
with the GAP distribution and the NetBSD package).
Corrections since bug fix level 1 include:
* A problem with the inversion routine for quaternions.
* A segmentation fault when appending to a length 0 compressed vector
over GF2.
* An error in the computation of inverses in quaternion algebras with
non-standard parameters.
* A problem in backtrack routines using `Suborbits' if the group has
fixed points in the range [1..max(Omega)].
* A problem with the linear algebra methods for Lie algebra cohomology.
* A Problem with inverting lists of compressed vectors over fields
of order greater than 2.
* An error in computing whether an element is in a Green's D equivalence
class or not.
* Problems with various functions (including GQuotient, IntScalarProduct,
NonnegIntScalarProducts, CharacterTableDirectProduct)
* Problems with various methods (including IsGreensLessThanOrEqual and
GroupHClassOfGreensDClass, AssociatedReesMatrixSemigroupOfDClass,
IsZeroSimpleSemigroup, IsomorphismReesMatrixSemigroup and
SandwichMatrixOfReesZeroMatrixSemigroup)
XXX A bug has been introduced into GAP which prevents the test suite
(zmodnz.tst) from working in this version. This will be fixed in
bug fix 4.

collection as math/gap.
GAP (Groups, Algorithms and Programs) is a free system for computational
discrete algebra. Its capabilities include computation involving
cyclotomic and finite fields, residue class rings, p-adic numbers,
multivariate polynomials and rational functions, vectors, matrices
and finite groups.
GAP can be copied and distributed freely for any non-commercial purpose.
