2002-10-08Update of GAP-4.3 (math/gap) to bug fix level 3.cjep6-4343/+4283
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. For full details, please see the "description3" file that comes with this package in ${PREFIX}/lib/gap4.3.
2002-08-21Initial import of GAP-4.3 (bug fix level 1) into the NetBSD packages cjep7-0/+4420
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.
