Higher homotopy of graphs has been defined in several articles. However, the existence of a long exact sequence associated to a pair (G, A) has not been touched at. We treat it here. Applied to the discrete spheres, this lead to interesting open questions. Higher homotopy of graphs has been defined in several articles.
