 Question 1
For two n-dimensional real vectors $P$ and $Q$, the operation $s(P,Q)$ is defined as follows:

Let $\mathcal{L}$ be a set of 10-dimensional non-zero real vectors such that for every pair of distinct vectors $P,Q \in \mathcal{L}, s(P,Q)=0$. What is the maximum cardinality possible for the set $\mathcal{L}$?
