In this talk, I will introduce group-invariant quantum latin squares and their connection to quantum isomorphisms. There will be some representation theory and finally, we will see a method of constructing Cayley graphs that are quantum isomorphic...

Consider a group G acting transitively on the vertices of an infinite, cubic (3-regular) graph Gamma such that the vertex stabilizers are infinite. We will see that if G is also edge-transitive on Gamma, then Gamma is the infinite cubic tree, and if...
