We present a family of high-order finite element approximation spaces on a pyramid, and associated unisolvent degrees of freedom. These spaces consist of rational basis functions. We establish conforming, exactness and polynomial approximation properties.
This work was originally in one paper, then split into two; it has now been recombined into one paper, with substantial changes from both of its previous forms
