Abstract

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.
