Topograph: A toolkit for Topological Graph Theory
by
Paul Bonnington
University of Auckland

We demonstrate a computational toolkit for applying minor operations to large classes of graphs and subsequent property checking. Embeddings in small surfaces can be checked, and isomorphism checking (by way of 'nauty') is included.

Results can be visualised and further analysed with a Graphical User Interface. Interaction with other packages such as 'magma' are demonstrated.
