Abstract: The codebreaker Alan Turing kicked off the study of what problems can be solved by computers. Many of them become easier when they have symmetries: finding a route is easier in a city with a grid of streets than in one with a chaotic layout. Colva Roney-Dougal,  who is the Director of the Centre for Interdisciplinary Research in Computational Algebra at St Andrews and a prominent expert in group theory,  explores how mathematics can be used to crack symmetrical problems, and shows that sometimes symmetry itself is the issue.
