Homogeneous models of C3 Monge geometries
  Distributions of Monge type are a class of strongly regular bracket-generating distributions introduced by I. Anderson, Zh. Nie and P. Nurowski. Their symbol algebras prolong to simple graded Lie algebras, thus allowing one to associate a parabolic geometry to any given Monge distribution. This article is devoted to the classification problem for homogeneous models of Monge distributions of type C3 in dimension eight, and is complementary to a paper by I. Anderson and P. Nurowski. The general classification algorithm, as well as most of its application to the particular problem, are joint work with Ian Anderson.
