n=N-2, then it means that there are at most two points in the last 4
columns, i.e. that at most two columns are used. And because all pairs of
points are equivalent, this is already handled by the wilson construction
with two truncated columns.
I believe it but please write it in a comment!

don't know why yet, so let's get this in.
