comment “Negative” versus “Minus”
As this the only mention of CS here, I'd like to expand upon it. There are computer languages, where negation is not expressed by "minus" symbol! J is one example, Calc is another one. In both the way to write negative numbers is to put an underscore before the digits. Obviously, there's also a binary representation, which writes numbers in an even more different way. So, even if historically both forms used to mean the same thing, to make it future-proof, it's better to distinguish between the two.

Thanks, this is interesting, however, it's also odd that this doesn't seem to ever happen. So I was wondering: is it just that the chance of it happening is extremely low, or maybe there's some other mechanics at play, that would prevent this from happening. I'll need to construct such an initial position, where this actually happens to convince myself.

Yeah, thanks, I'd have to work on that. Sure $Scc$ was meant to be $S(c+c)$.

@GitGud that is the original syntax of the book (at least the edition that I have).

@JaycobColeman yay! Thanks a lot! You probably could post it as an answer so I could accept it.
