Query: Three Form Inflation   It is noted that inflation driven by a three form with arbitrary self
coupling satisfies a consistency relation $n_S-1=2n_T$, between spectral
indices of scalar and tensor cosmological perturbations. The standard
consistency relation for the ratio of the amplitudes of perturbations is only
valid for quadratic self coupling of the three form.
