Software Carpentry lesson on GAP

Alexander Konovalov wrote two blog posts about the Software Carpentry lesson on GAP. The first one is “Programming with GAP”, written for the Software Carpentry website and telling how the lesson has been established. The second one is “Publishing Software Carpentry lesson on GAP” which contains more details about the research-like problem on which the lesson is based.

Computational Mathematics with Jupyter

Jointly with the Horizon 2020 OpenDreamKit project, we are currently organising the workshop “Computational Mathematics with Jupyter”. It will take place at the International Centre for Mathematical Sciences in Edinburgh on 16-20 January 2017. Please see the workshop website here for further details.

Towards practical methods to compute with hyperbolic groups

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 that we need to have a usable and publicly available GAP implementation of these. The progress report on this visit is available here. The work on the new GAP package continues…

There is no McLaughlin geometry

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 wrote a blog post about the significance of this result here.
