## Idea

The higher order frame bundle is higher order jet version of the frame bundle.

Its structure group is the jet group $GL^k$ of the given order.

In synthetic differential geometry/differential cohesion the higher order frame bundle is the bundle of infinitesimal disks of the given order. It is the principal bundle (principal infinity-bundle) to which the infinitesimal disk bundle is the associated bundle (associated infinity-bundle)
