This is to announce the availibility of the third upgrade for GAP 3.2.
This upgrade brings version 3 release 2 patchlevel 2 (V3R2P2) to version
3 release 2 patchlevel 3 (V3R2P3). The priority of this upgrade is
This upgrade adds adds a group of size 96 that was missing from the
library of solvable groups of size <= 100. It also adds symmetric groups
on 0 and 1 points.
This upgrade fixes the reported problem with subgroups in a composition
series of a permutation group having a trivial elements list. Also the
functions for permutation groups are a little bit more carefull to avoid
creation of unnecessary lists. Coset enumerations in finitely presented
groups will now enter a break loop if more than a certain number of
cosets have been defined, to give the user the choice to abandon the
enumeration. A problem with the computation of double cosets in very
small groups is fixed. A problem in the implementation of Dixon's method
to compute the character table of a group is fixed. Two functions that
assumed that the trivial character is always first in the character table
were fixed. 'DisplayCharTable' now handles character tables that have no
powermap. A function 'InterpolatedPolynomial' was added. The function
that divides polynomials now checks if the divisor and not the dividend
is nonzero. An incorrect test in the function that composes mappings is
A function 'LogInputTo' was added to the kernel. The kernel didn't know
about the new ranges with three operands, so the third operand was
sometimes deleted by the garbage collection, leading to address errors
and core dumps.
The upgrade is available as file 'upg3r2p3.dif.Z' on the 'ftp' server
'samson.math.rwth-aachen.de'. It should be available on the other 'ftp'
servers soon. This time I do not send out this upgrade as e-mail, it is
simply too large (about 100 KBytes 'compress'-ed).
First unpack the upgrade with 'uncompress upg3r1p3.dif.Z'. Then read the
beginning of the unpacked file 'upg3r2p3.dif', which contains
instructions how to apply this upgrade.
