Summary: Given a symmetric polynomial [ `$( k)] \bar k$ as the vertex set and adjacencies corresponding to the zeroes of [ `$( k)] \bar k / k)$ to the automorphism group of certain classes of Galois graphs. Finally, an application concerning modular curves classifying pairs of isogeny elliptic curves is revisited.
Keywords: Galois, graph, digraph, tree, automorphism
