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

Next major GAP release: GAP 4.10.0

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

Carnival of Mathematics #161

Welcome to the 161th Carnival of Mathematics. This is a monthly digest of selected mathematical blogs, hosted each month on a different site. The 1st Carnival has been published in February 2007, so this tradition already continues for more than 11 years. Following the Carnival’s tradition, first we collect some interesting facts about 161 = 7 Carnival of Mathematics #161

Algorithms for black box groups

CoDiMa partially supported the visit of Prof. Alexandre Borovik (University of Manchester) to Dr Sukru Yalcinkaya (Istanbul University) on 8-21 September 2018. They reported the following: In this short period of very intensive work in a small group (A. Borovik, S. Yalcinkaya (Istanbul University), and M. Lavrauw (Sabanci University)) we achieved a significant further progress Algorithms for black box groups

GAP Jupyter interface included in GAP 4.9.2 release

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

Computations in small overlap monoids

For several days in June 2018, Mark Kambites (Manchester) visited James Mitchell in St Andrews, supported by the CoDiMa research visits programme. The visit allowed Mark Kambites and James Mitchell to discuss algorithms for performing computations in small overlap monoids. Efficient algorithms for various problems in this important class of finitely presented monoids were developed by Computations in small overlap monoids

Symmetry vs Regularity: The first 50 years since Weisfeiler-Leman stabilization

Madeleine Whybrow reports: With the support of CoDiMa, I attended the conference “Symmetry vs Regularity: The first 50 years since Weisfeiler-Leman stabilization” in Pilsen, Czech Republic. It was a very impressive event and nearly all of the major contributors to the field of algebraic graph theory over the past 50 years were present. There were some Symmetry vs Regularity: The first 50 years since Weisfeiler-Leman stabilization
