Query: Haruspicy 2: The anisotropic generating function of self-avoiding
  polygons not D-finite   We prove that the anisotropic generating function of self-avoiding polygons
is not a D-finite function - proving a conjecture of Guttmann and Enting. This
result is also generalised to self-avoiding polygons on hypercubic lattices.
Using the haruspicy techniques developed in an earlier paper we are also prove
the form of the coefficients of the anisotropic generating function, which was
first conjectured by Guttmann and Enting.
