Query: On the $S_n$-equivariant Euler characteristic of moduli spaces of
  hyperelliptic curves   The generating function for $S_n$-equivariant Euler characteristics of moduli
spaces of pointed hyperelliptic curves for any genus g>1 is calculated. This
answer generalizes the known ones for genera 2 and 3 and answers obtained by J.
Bergstrom for any genus and n<8 points.
