-------------------------------------------------------------------------------- Fedora Update Notification FEDORA-2026-04122a95a8 2026-08-21 05:18:12.044338+00:00 --------------------------------------------------------------------------------
Name : gap-pkg-aclib Product : Fedora 44 Version : 1.4 Release : 1.fc44 URL : https://gap-packages.github.io/aclib/ Summary : Almost Crystallographic groups library for GAP Description : The AClib package contains a library of almost crystallographic groups and some algorithms to compute with these groups. A group is called almost crystallographic if it is finitely generated nilpotent-by-finite and has no nontrivial finite normal subgroups. Further, an almost crystallographic group is called almost Bieberbach if it is torsion-free. The almost crystallographic groups of Hirsch length 3 and a part of the almost crystallographic groups of Hirsch length 4 have been classified by Dekimpe. This classification includes all almost Bieberbach groups of Hirsch lengths 3 or 4. The AClib package gives access to this classification; that is, the package contains this library of groups in a computationally useful form. The groups in this library are available in two different representations. First, each of the groups of Hirsch length 3 or 4 has a rational matrix representation of dimension 4 or 5, respectively, and such representations are available in this package. Secondly, all the groups in this library are (infinite) polycyclic groups and the package also incorporates polycyclic presentations for them. The polycyclic presentations can be used to compute with the given groups using the methods of the Polycyclic package. -------------------------------------------------------------------------------- Update Information: Changes in version 1.4: Convert the manual to GAPDoc, built with AutoDoc via makedoc.g Fix typos, stale cross references and markup glitches in the manual Update the references to the two Dekimpe-Eick papers to their published versions Various janitorial changes -------------------------------------------------------------------------------- ChangeLog: * Thu Aug 13 2026 Jerry James <[email protected]> - 1.4-1 - Version 1.4 -------------------------------------------------------------------------------- References: [ 1 ] Bug #2515027 - gap-pkg-aclib-1.4 is available https://bugzilla.redhat.com/show_bug.cgi?id=2515027 -------------------------------------------------------------------------------- This update can be installed with the "dnf" update program.
