For two n-dimensional real vectors P and Q, the operation s(P,Q) is defined as follows: s(P,Q) = Sum over i=1 to n of (P[i] . Q[i]). Let L be a set of 10-dimensional non-zero real vectors such that for every pair of distinct vectors P, Q in L, s(P,Q) = 0. What is the maximum cardinality possible for the set L?
