comment Pairwise Maximum Metric
just one doubt , for $X = 1$ , $h(X)$ will still be $11$ as the sum which is subtracted goes from $1$ to $X-1$ and in the case of $X = 1$ it does not get subtracted.

comment Pairwise Maximum Metric
And in case of 1D vectors , I have counted them like this , that they will be points on a line , and if X is the fixed value then any set must contain 2 points at distance of X , between those two point there are X - 1 points which can be added in to the set or not , that is why the count I got was $2^{X-1}$
