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.

British Combinatorial Conference 2019

From 29th July-2nd August Rosemary Bailey, Peter Cameron, and Siavash Lashkarighouchani attended the British Combinatorial Conference at the University of Birmingham. Peter organised a mini-symposium on Designs and Latin Squares, at which Rosemary spoke on ‘Substitutes for the non-existent square lattice design for 36 treatments’. Peter also contributed a talk on ‘Hall-Paige and synchronization’. At the conference business meeting, Peter was re-elected chair of the British Combinatorial Committee, a position he has held for 25 years.
