Cyclically presented groups, such as the Fibonacci groups, are ones defined by a presentation with a cyclic symmetry. Circulant matrices and graphs are ones with a similar symmetry. Circulants play a role in understanding the structure of cyclically presented groups and, conversely, cyclically presented groups can be used to obtain results on circulants. I will discuss a range of algebraic and number theoretic techniques that can be applied to such problems.
