Query: An example of the geometry of a 5th-order ODE: the metric on the space
  of conics in ${\mathbb{CP}}^2$   As an application of the method of [4], we find the metric and connection on
the space of conics in $\mathbb{CP}^2$ determined as the solution space of the
ODE eqn(1). These calculations underpin the twistor construction of the Radon
transform on conics in $\mathbb{CP}^2$ described in [5]. Two further examples
of the method are provided.
