  A differential bulk-surface relation of the lagrangian of General Relativity
has been derived by Padmanabhan. This has relevance to gravitational
information and degrees of freedom. An alternate derivation is given based on
the differential form gauge theory formulation of gravity due to Gockeler and
Schucker. Also an entropy functional of Padmanabhan and Paranjape can be
rewritten as the Gockeler and Schucker lagrangian.
