There was a problem hiding this comment.
I believe you can make this b = prod(A1, B.one()).

- br1 = B0.delta()**r * B0(prod(B0(_) for _ in br0_left[1:]))
+ br1 = B0.delta()**r * prod(map(B0, br0_left[1:]), B0.one())Also, do you mind renaming _ to say br or something sensible? Variable names shouldn't start with underscores if they are used.
