Separability and complete reducibility of subgroups of the Weyl group of a simple algebraic group of type E7E7

Let G be a connected reductive algebraic group defined over an algebraically closed field k  . The aim of this paper is to present a method to find triples (G,M,H)(G,M,H) with the following three properties. Property 1: G is simple and k has characteristic 2. Property 2: H and M are closed reductive subgroups of G   such that H
