Demonstrating that rigour is important
This is a bit off topic, but related to gowers last sentence. I don't really like the idea of having to justify that proof is important. I think asking the question Why?' is natural and important in its own right. Curiosity appears to be built in to us. 'Why?' drives a significant portion of the sciences and humanities and everyday life. It would be hard to deny that our active desire to satisfy this inbuilt curiosity is at least partially responsible for human advance (whatever that is). For me, trying to find specific examples where having a proof saves lives' cheapens the whole process.

Integral positive definite quadratic forms and graphs
I know $K_n$ is the complete graph and $C_n$ is a cycle graph and I am assuming that $E_n$ is the empty graph. What are $A_n$ and $D_n$?

Neat idea. I think you might mean $A^{m1}$? Also, don't you need to sum all of the elements in the matrix, not just those above and on the diagonal?

Indeed, I mean vectors. I have fixed the title. I have made a bit of a mess of this question! And multiplying Peters answer by $m!$ as you have said give the desired result.

My comment makes no sense! Repetition implies that $d(S) = 0$. I'm going to have to stop and think about what I am asking.

Hi Peter, I don't think this is correct. With ''msubsets of $\{1,2,\cdots,n\}$'' you are not allowing repetition, but I mean for the question to allow repetition. This is wholly my fault, I should never have called $S$ a set!
