CIRCA

The Centre for Interdisciplinary Research in Computational Algebra (CIRCA) was established in 2000 to foster new and existing collaborative research between members of the Schools of Computer Science and of Mathematics and Statistics in the area of computational abstract algebra.

The Centre undertakes mathematical research with computer assistance, develops new techniques for computation in abstract algebra and develops and distributes software implementing these techniques. This work is supported by research grants from the EPSRC, the Leverhulme Trust, the British Council, the European Commission and the Royal Society of Edinburgh.

The Centre also organises conferences, seminars and training courses and coordinates the international efforts to develop maintain and promote the GAP (groups, algorithms and programming) software package, a leading integrated system for computational discrete mathematics and algebra.

News and Events

Visits and conferences – May 2017


  • The London Combinatorics Colloquia took place at Queen Mary University of London on 10th May, when Sophie Huczynska gave a talk “Graph classes under homomorphic image order”, and the following day at the London School of Economics. Whilst there Peter Cameron chaired a meeting of the British Combinatorial Committee, also attended by Nik Ruskuc.
  • Nik Ruskuc visited Robert Brignall at the Open University for a week to pursue their joint research project about the property of well quasi order in combinatorics.
  • Colin Campbell, Edmund Robertson and Nayab Khalid attended the 40th Groups in Galway meeting at NUI Galway from 18-20th May.

Semigroups 3.0 Hackathon


It’s been a long time coming, but Semigroups 3.0 is nearly ready for release.  We’re going to have a hackathon to squash all the remaining bugs, add documentation, replace TODOs, and generally polish and tweak the package until it’s ready to be released! The kick-off is at 11am on Monday May 29th in Maths Lecture Theatre D. Everyone is welcome to join!
