A Semple Approach to Goursat: The Multi-Flag Case

In this note we summarize our results from earlier work with the Monster Tower (A Monster Tower Approach to Goursat Multi-Flags). In particular, we give an overview of the problem of classifying the orbits within a tower of fibrations with fibers diffeomorphic to projective planes. Included in this note is one new result that was not in our previous work.
