In this paper we formulate and study the problem of representing groups on graphs. We show that with respect to polynomial time Turing reducibility, both abelian and solvable group represent ability are all equivalent to graph isomorphism, even when the group is presented as a permutation group ...

2.1 Directed Acyclic Graphs Suppose G is a rooted directed acyclic graph (DAG), that is, a DAG with a unique vertex with indegree zero. We call that vertex the root of G, denoted by . Also, we call the graph U(G) obtained from G by ignoring the directions of its edges the underly...
