Pkgsrc fixes:
1) Install trans directory.
Official bug fixes since bug fix 4:
1) A wrong return format for `IsomorphicSubgroups' applied to cyclic groups.
2) A wrong `true' result of `IsSubset' for certain algebras.
3) Segmentation faults and other strange behaviour when assigning
finite field elements of different characteristics into compressed vectors
4) A bug in the subgroup conjugation test for permutation groups that are
not subgroups.
5) A missing method for `BaseOrthogonalSpaceMat'.
6) A missing `Set' call in the construction of the global variable
`AUTOLOAD_PACKAGES'.
7) A wrong display string of the numerator in rational functions returned
by `MolienSeries' (in the case that the constant term of this numerator
is zero).
8) A strange behaviour of `Intersection' for the case that a strictly
sorted list is the unique entry of the list that is given as the
argument; in this situation, this entry itself was returned instead of
a shallow copy.
9) An error in the basis of a product space of algebras.
10) Possibly wrong result of `Centre' for pc groups.
11) Possibly wrong result of `DirectSumDecomposition' for matrix Lie algebras.
12) An error in `LieNormalizer', `LieCentralizer' for zero subspaces.
13) An error in the computation of matrices of adjoint modules.
14) A strange error message when constructing the simple Lie algebra of type
B1.
15) An error in `ModuleByRestriction'.
16) An error in `IrrBaumClausen' for the trivial group.
17) An error with vector space bases of row spaces over fields which
neither are prime fields nor contain all entries of the vectors.
18) An error with `IsMonomial', when it uses the function
`TestMonomialFromLattice' (i.e., in hard cases, likely for characters of
nonsolvable groups).
Errors 1, 3, 5, 6, 9, 12, 13, 14 and 16 may cause GAP to stop with an error
message, errors 2, 4, 7, 10, 17, and 18 may cause wrong results.
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.
