Abstract
We consider the space of configurations of points in satisfying the condition that no three of the points lie on a line. For , we compute as an –representation. The cases are computed via the Grothendieck–Lefschetz trace formula in étale cohomology and certain “twisted” point counts for analogous spaces over .
