I'm a bit uneasy about not having math yet, but that can be fixed. The main concern about merging is getting a slightly more descriptive name for the element like C2DoubleAlfeld. Other suggestions welcome.

I appreciate the generality here. However, the math + numpy is a bit unclear. For example, how does this go from the 2x2 jet to 3x3 Hessian map (often called Theta) in the zany papers? Maybe a comment is in order.

I guess if we write out the maths in a paper this will all become clearer to me?

I think I'm ok with this once we land on the final version of the names. Once The Paper is written on the transformations, we can link to it and the mysterious code will be at least documented on the arXiv.
