30
31
32v1.00: The package has been accepted by the GAP Council. Changes proposed by Alice Niemeyer and the anonymous referee:
33- Added in AllGeneratorsCyclicPGroup a test for the arguments to be of the correct type.
34- Minor changes to the documentation.
35
36
37
38v0.04: Changes proposed by Alice Niemeyer and the anonymous referee:
39- Documentation written in GAPDoc. Minor modifications in the documentation.
40- Changed names of the old `Why' functions:
41  WhyAreNotMutuallyFPermutableSubgroups -> OnePairShowingNotMutuallyFPermutableSubgroups
42  WhyAreNotMutuallyPermutableSubgroups -> OnePairShowingNotMutuallyPermutableSubgroups
43  WhyAreNotTotallyFPermutableSubgroups -> OnePairShowingNotTotallyFPermutableSubgroups
44  WhyAreNotTotallyPermutableSubgroups ->OnePairShowingNotTotallyPermutableSubgroups
45  WhyIsNotConjugatePermutable -> OneConjugateSubgroupNotPermutingWith
46  WhyIsNotCPTGroup -> OneSubnormalNonConjugatePermutableSubgroup
47  WhyIsNotFPermutable -> OneFSubgroupNotPermutingWith
48  WhyIsNotPermutable -> OneSubgroupNotPermutingWith
49  WhyIsNotPSNTGroup -> OneSubnormalNonSNPermutableSubgroup
50  WhyIsNotPSTGroup -> OneSubnormalNonSPermutableSubgroup
51  WhyIsNotPTGroup -> OneSubnormalNonPermutableSubgroup
52  WhyIsNotSNPermutable -> OneSystemNormaliserNotPermutingWith
53  WhyIsNotSPermutable -> OneSylowSubgroupNotPermutingWith
54  WhyIsNotTGroup -> OneSubnormalNonNormalSubgroup
55  WhyIsNotWeaklyNormal -> OneElementShowingNotWeaklyNormal
56  WhyIsNotWeaklyPermutable -> OneElementShowingNotWeaklyPermutable
57  WhyIsNotWeaklySPermutable -> OneElementShowingNotWeaklySPermutable
58  WhyIsNotWithSSubpermutizerCondition -> OneSubgroupInWhichSubnormalNotSPermutable
59  WhyIsNotWithSubnormalizerCondition -> OneSubgroupInWhichSubnormalNotNormal
60  WhyIsNotWithSubpermutizerCondition -> OneSubgroupInWhichSubnormalNotPermutable
61- Modified functions about totally and mutually permutable products to
62  avoid use of AllCyclicSubgroups. We use Zuppos instead. The function AllCyclicSubgroups has been deleted.
63- Modified Permutizer function to detect permutable subgroups and to
64use an enumerator instead of all cyclic subgroups.
65- Added a probabilistic test to detect lack of permutability before
66applying deterministic test in IsPermutable and IsIwasawaSylow.
67- Modified the type of arguments of OneFSubgroupNotPermutingWith and
68IsFPermutable, now the third argument is a list of subgroups of the
69whole group.
70- Modified the arguments of AreMutuallyFPermutableSubgroups,
71AreTotallyFPermutableSubgroups, OnePairSwhowingNotMutuallyPermutable
72and OnePairSwhowingNotMutuallyPermutable to include lists of subgroups of U and
73V, respectively. This allows a greater generality.
74- Deleted functions IsPERMUTPSolvable and IsPERMUTPNilpotent since there
75are methods for non-soluble groups available in GAP 4.7.2. These
76functions have been replaced by IsPSolvable and IsPNilpotent in the
77code. GAP 4.7.2 is required now.
78
79
80v0.03: Deleted InstallFactorMaintenance and InstallSubsetMaintenance
81  statements due to an error in the assignment of IsPSTGroup to
82  quotient groups.
83
84
85v0.02: changes proposed by Leonhard Soicher before refereeing and others:
86- Moved files *.g to lib directory.
87- Created directory htm to include html files.
88- Changed PackageInfo.g to be correctly validated.
89- Rearranged documentation (only chapters).
90- Added a test.
91- Moved IsSylowTowerGroup to psoluble.g[di].
92- Applied Transatlantic.
