comment Chromatic polynomial of a grid graph
The picture in the post suggests that the solution for general $n$ and $m$ is not known. In particular, some well known mathematicians did not know how to solve it.

comment An inequality related to the number of binary strings with no fixed substring
@RossMillikan I've checked the conjecture for all $n$ up to $12$ and $|f| \leq n$ and it appears to be true.

comment An inequality related to the number of binary strings with no fixed substring
@RossMillikan Observe that $S_n(f) = S_n(\overline{f})$ where $\overline{f}$ is the string obtained by inverting the bits in $f.$ Hence you can always assume both start with $0$
