In this talk, I will introduce a class of groups called generalised triangle groups. These groups were originally defined by Stallings, and later studied by Caprace, Conder, Kaluba, and Witzel as candidates for non-residually finite hyperbolic groups. Generalised triangle groups have corresponding CW complexes, which allow us to study the groups using combinatorial and geometric techniques. I will demonstrate this by examining cone types for non-positively curved k-fold triangle groups.
