Symmetries of discrete objects

This research deals with discrete objects such as graphs, networks, maps, tessellated surfaces, polytopes and 3-manifolds, which have high degrees of symmetry under particular conditions.

Typically, the symmetries form a group that can be presented in a particular form, this is associated with the kind of object being considered. Examples can be analysed in terms of the object itself, or the group, or even the ambient space.

Also new examples, or new families of examples, can be constructed using knowledge of the group structure. Use of the computational algebra package MAGMA can be very helpful in their construction and analysis and in solving open problems.
