    Hm, I’ll have to come back to this. I don’t like the erasure of “baby form of” (Birkhoff duality) – the finite form of the duality not being full-fledged “adult” Birkhoff duality – but perhaps “finite” or “finitistic” instead of “baby” and you’d be happy?

    There is at least one more strikeout whose appropriateness I’d have to consider when I have more time.
