 > (b) I could not make the line `S(x) := -\sum_{x^L\neq x} S(x^L) \times
 x^R` work so I changed it to `S(x) := -\sum_{x^L!=x} S(x^L) \cdot x^R`.
 For some reason the latex interpreter does not recognize `\neq` or
 `\times`...I fought with it for over an hour and just gave up.

 Missing an "r" at the beginning of the quotes for the docstring? If so,
 then the `\t` in `\times` would be interpreted as a tab, `\n` in `\neq` as
 a newline.
