Abstract

We find a general solution to the unique 7th order ODE admitting ten dimensional group of contact symmetries. The integral curves of this ODE are rational contact curves in \PP3\PP^3 which give rise to rational plane curves of degree six. The moduli space of these curves is a real form of the homogeneous space Sp(4)/SL(2)Sp(4)/SL(2).
