Abstract
For each n≥5n≥5, we give an SnSn-equivariant basis for H4(M0,n,Q)H4(M0,n,Q), as well as for H2(n-5)(M0,n,Q)H2(n-5)(M¯0,n,Q). Such a basis exists for H2(M0,n,Q)H2(M0,n,Q) and for H2(n-4)(M0,n,Q)H2(n-4)(M0,n,Q), but it is not known whether one exists for H2k(M0,n,Q)H2k(M0,n,Q) when 3≤k≤n-63≤k≤n-6.
