Four new sequences capturing the perimeter polynomials and sprawl have been
created.

https://oeis.org/A338210 (fixed perimeter)
https://oeis.org/A338211 (free perimeter)
https://oeis.org/A338212 (fixed sprawl)
https://oeis.org/A338213 (free sprawl)

b-files for the first two, still to come.

Sean.
