comment Does a product of matrices have eigenvalue 1
This depends crucially on the set of sequences that you are interested in. Is it all sequences of length $k$? If not, what?

comment Drawing lines and removing squares - an Alice and Bob game
The proper questions to ask are: Given $N$, which player wins? And how?

comment Some weird “system” of inequalities in nonnegative integers.
You should not have responded so quickly to SPG's question! $i≤j≤k≤l$ is not consistent with $1≤i,j,k,l≤17$.

Erdős, not Erdös.

comment what is the meaning of “consecutive triple points”?
Are you sure it said that? It's not proper English.

comment Reducing factoring prime products to factoring integer products (in average-case)
You are being sloppy here. N = PQ can always be factorised -- it just can't be factorised (as far as we know) in polynomial time (with non-negligible probability).

comment Which conjectures only need the Grand Riemann Hypothesis to become genuine theorems?
The Wikipedia article (en.wikipedia.org/wiki/Grand_Riemann_hypothesis) has this wonderful remark: "The Siegel zero, conjectured not to exist, is a possible real zero of a Dirichlet L-series, rather near s = 1."

comment real roots for polynomials
@Willie: I think $Q_k$ is just the quotient when $P_{k-1}$ is divided by $P_k$.

comment Rolling-ball game
Let's not forget that there are three possibilities: 1. There exists an infinite game. 2. There exist arbitrarily long finite games. 3. There exists $n$ such that no game is longer than $n$. So gowers and Gerhard could both be right, on the sphere and not just the torus. @Joseph: Nice pictures!
