We describe an algorithm to compute the stable multiplicity of a family of irreducible representations in the cohomology of ordered configuration space of the plane. Using this algorithm, we compute the stable multiplicities of all families of irreducibles given by Young diagrams with 23 boxes or less up to cohomological degree 50. In particular, this determines the stable cohomology in cohomological degrees 0 <= 𝑖 <= 11. We prove related qualitative results and formulate some conjectures.

In this article we study adjoint hypersurfaces of geometric objects obtained by intersecting simple polytopes with few facets in P^5 with the Grassmannian Gr(2,4). These generalize the positive Grassmannian, which is the intersection of Gr(2,4) with the simplex. We show that if the resulting object has five facets, it is a positive geometry and the adjoint hypersurface is unique. For the case of six facets we show that the adjoint hypersurface is not necessarily unique and give an upper bound on the dimension of the family of adjoints. We illustrate our results with a range of examples. In particular, we show that even if the adjoint is not unique, a positive hexahedron can still be a positive geometry.
