GAP 4.10.1 has been released in February 2019 and can be downloaded from the GAP website here. In addition to updates in the core GAP system, it contains 145 packages, including updated versions of 35 packages from GAP 4.10.0 distribution, and also five new packages: MajoranaAlgebras by Markus Pfeiffer and Madeleine Whybrow, which constructs Majorana … GAP 4.10.1 release
The next major release of GAP 4.10.0 has been announced on 12 November 2018. Its complete overview with links to the GAP documentation and GitHub pull requests can be found here. Alternative distributions – Gap.app for macOS and GAP Docker container have been updated too. You can check the status of standard tests of GAP packages from … Next major GAP release: GAP 4.10.0
The new minor release of GAP, version 4.9.2, is now available for download from the GAP website at https://www.gap-system.org/Releases/. It includes the new JupyterKernel package by Markus Pfeiffer which provides a so-called kernel for the Jupyter interactive document system. This package requires Jupyter to be installed on your system (see instructions here). It also requires … GAP Jupyter interface included in GAP 4.9.2 release
The new major release of GAP, version 4.9.1 release, is now available for download from the GAP website at https://www.gap-system.org/Releases/. The complete description of these and other changes, with links to the documentation and to GitHub pull requests is available here. Please also see the release announcement in the GAP Forum.
I spent a week in St Andrews working with Markus Pfeiffer on an ongoing project which we are working on writing and implementing an algorithm to construct 2-closed Majorana representations. Funding for this trip was provided by CoDiMa. Majorana algebras are non-associate algebras used to study the Monster group and its subgroups. They can be studied … Madeleine Whybrow’s second visit to St Andrews
GAP 4.8.8 release, which also includes 30 package updates, has been announced today and is now available for download from the GAP website. Please also see the release announcement in the GAP Forum.
After meeting at the Workshop on Permutation Groups: Methods and Applications in Bielefeld in Germany, Markus Pfeiffer became interested in some computational work which I am developing as part of my PhD. He kindly invited me to St Andrews to spend a week working together on my code. Funding for this trip was provided by … Visitor Madeleine Whybrow: Constructing Majorana Representations in GAP
Yet again I attended the Nikolauskonferenz in Aachen this year, funded by CoDiMa. At the meeting Chris Jefferson and I presented our work with Rebecca Waldecker, and co-funded by CoDiMa, on search and canonical images in permutation groups. A recent submission can be found here, and a further one is coming out soon. Another notable … Nikolaus conference 2016
In October 2016, Markus Pfeiffer visited Alan Logan in Glasgow to work on the practical implementations of methods to compute with hyperbolic groups. This is an important direction of research, and it was once more highlighted at the “Computation in geometric and combinatorial group theory” workshop at the ICMS in Edinburgh in July this year … Towards practical methods to compute with hyperbolic groups
This summer Leonard Soicher (Queen Mary) and Patric Östergård (Aalto) published the preprint with the same title, in which they successfully used GAP to solve a 40-year-old problem about the existence of a partial geometry which has the McLaughlin graph as its point graph. The calculation, which used GAP and its GRAPE package, took about 250 core-years. Peter Cameron … There is no McLaughlin geometry
