So just to fix bundle notation, we let \(H\) be the structure group of a bundle \(P_H\) over a base space \(B\). We use \(\pi\) for the projection map. We've reserved the variation in the \(\pi\) orthography for the field content, and we try to use right principal actions. I'm terrible with left and right, but we do our best. We use \(H\) here, not \(\mathcal{G}\), because we want to reserve \(\mathcal{G}\) for the inhomogeneous extension of \(H\) once we move to function spaces.
