A digraph G = (V, E) is primitive if, for some positive integer k, there is a u โ†’ v walk of length k for every pair u, v of vertices of V . The minimum such k is called the exponent of G, denoted exp(G). The exponent of a vertex u โˆˆ V , denoted exp(u), is the least integer k such that there is a u โ†’
