Abstract
For a prime p>2 and q=p^n, we compute a finite generating set for the SL_2(F_q)invariants of the second symmetric power representation, showing the invariants are a hypersurface and the field of fractions is a purely transcendental extension of the coefficient field. As an intermediate result, we show the invariants of the Sylow psubgroups are also hypersurfaces.
