Revision history [back]

Looking through the source code of sage/geometry/lattice_polytope.py I found the method which is calling PALP, it is poly_x. In the documentation for poly_x there is an example which suggests that PALP has certain limits which are determined at compile time:

IMPORTANT: PALP requires some parameters to be determined during
   compilation time, i.e., the maximum dimension of polytopes, the
   maximum number of points, etc. These limitations may lead to errors
   during calls to different functions of these module.

Thus, it looks like you can't change POLY_Dmax unless you rebuild PALP manually. It might be a good idea to post your question to the sage-support list and mention the authors of the Sage interface to PALP: Andrey Novoseltsev and William Stein.
