The space (eq:jetambiguity) is the unrestricted supported ambiguity with the fixed response-normal bound. It is not automatically the partial-diagonal class, a normalized contact class, or a space of admissible maps on presentations.

A finite normal-order bound does not make this ambiguity finite-dimensional. For example, when and , already at the distributions

give an infinite linearly independent family. A further bound on the tangential order is needed for a finite-dimensional space.
