Orbital graphs and constructive matrix recognition
Paula Hähndel (Martin-Luther-Universität Halle-Wittenberg) writes on her visit to St Andrews in Spring 2019, supported by CoDiMa:
“My stay in St Andrews was a great opportunity to meet the local GAP community. I was encouraged to continue my improvements of parts of the GAP documentation, and I used some of my time during my stay to do so. I also continued to discuss some ideas about orbital graphs with Markus Pfeiffer. One part of this was discussing ways to construct groups that have interesting orbital graphs, which would provide good test cases for the search algorithms that are developed by Wilf Wilson, Chris Jefferson and Markus.
I also gave a talk about constructive matrix group recognition and the discussion (mainly with Mun See Chang, Wilf and Chris) continued afterwards. We also discussed many of the details that are needed for implementation, but that were not addressed in the talk. This hopefully was a good preparation for the Summer School on Matrix Group Recognition in Aachen this year that us four will attend together. I am thankful for the opportunity to come. It was a really nice and productive time in St Andrews.”
