Intersection numbers on ℳ ¯ g,n. We introduce the package HodgeIntegrals, which calculates top intersection numbers among tautological classes on ℳ ¯ g,n . As an application, we show that the tautological ring of the moduli space ℳ 3,0 λ 2 of genus three curves whose dual graph has at most one loop is not Gorenstein.
