    added the statement, here, that the homotopy type of jet groups is that of the general linear groups (and that the canonical map exhibits the homotopy equivalence).

    Vaguely related to this, I have also added at integrability of G-structures – Traditional definition and at torsion of G-structures – Idea some more pointers on the order-kk torsion/infinitesimal integrability, mostly with pointers to page and verse in Guillemin65.
